Inno Setup: copy file to multiple destinations defined by user - file

Question

During installation process user has ability to install number of some service instances (Service1- ServiceN). All the differences between these services - content of configuration files(actually there is only one executable in /Product_Root/run wich is called with different command-line params).Configuration files situated in ProductRoot/ServiceX/conf.
Folders structure looks like :
/Product_Root
----/bin
----/doc
----/Service1
---------/conf
----/Service2
---------/conf
...
----/ServiceN
---------/conf
In ProductRoot/ServiceX/conf is situated, for example, service.properties file with these contents:
#...
ServiceRoot = <%ROOT_DIRECTORY%>
ListenPort = <%PORT%>
#...
Also in /Product_Root/bin scripts for each service startup should be present:
For example :
/Product_Root/bin/Service1.run.cmd
/Product_Root/bin/Service2.run.cmd
...
/Product_Root/bin/ServiceN.run.cmd
...
Script file structure is:
service.exe ../<%SERVICE_NAME%>/conf/service.properties
All values (like <%SERVICE_NAME%>,<%PORT%> etc.) are set by user during setup process for each Service.
Amount of services is also set by user and may vary between 1 (by default) and 20-30.
In case of single service - there is no problem.
Files being copied, directories created using
[Files]
Source: {#FilesPath}\bin\*.*; DestDir: {app}\{#FileLocationPrefix}\bin; Flags: ignoreversion restartreplace
Source: {#АilesPath}\conf\*.*; DestDir: {app}\{#FileLocationPrefix}\{code:GetServiceName}\conf; Flags: ignoreversion recursesubdirs createallsubdirs restartreplace;
[Dirs]
Name: {app}\{#FileLocationPrefix}{code:GetServiceName}\conf
After in ssPostInstall step wildcards replace performed in copied files.
Question.
is it possible using Inno Setup + ISTool to do the same in case of number of services?
E.g. something like that :
[Files]
#for (i = 0; i < ServiceCount(); ++i)
Source: {#АilesPath}\conf\*.*; DestDir: {app}\{#FileLocationPrefix}\{code:GetServiceName| i}\conf; Flags: ignoreversion recursesubdirs createallsubdirs
where i — is actually configuration number.
I.e. is it possible to use information received from user during installation process in [File], [Dirs] etc. sections for multiple copying of the same files in different directories?
For copying single file in number of files with different names set by user during install process?
Or I just going in the wrong direction?

Answer 1

So, currently I've done this in such way. Comments are welcome.
For creating and copying all files:
#define MaxFEInstances 20
...
#sub CreateConf
Source: {#FilesPath}\conf\*.*; DestDir: {app}\{#FileLocationPrefix}{code:GetServiceName|{#counter}}\conf; Flags: ignoreversion recursesubdirs createallsubdirs restartreplace; Check: InstanceSetupRequired({#counter}); Components: main
#endsub
#for {counter = 0; counter < MaxInstances; ++counter} CreateConf
enter code here
...
function InstanceSetupRequired(InstanceNum: Integer): Boolean;
begin
Result := InstanceNum < Instances;
end;
For separate files it looks pretty same.
