CHOOSE BETWEEN MULTIPLE CONFIG SUP WHILE STARTING CREO

See, for example multiple-choices-menu-on-batch-file 

I've adapted the example by David Ruhmann in the link above to your scenario, see if it's something you can use: 

:: Hide Command and Set Scope
@echo off
setlocal EnableExtensions

:: Customize Window
title Creo Configurations

:: Menu Options
:: Specify as many as you want, but they must be sequential from 1 with no gaps
:: Step 1. List the Application Names
set "App[1]=Creo for company A"
set "App[2]=Creo for company B"

:: Display the Menu
set "Message="
:Menu
cls
echo.%Message%
echo.
echo. Menu
echo.
set "x=0"
:MenuLoop
set /a "x+=1"
if defined App[%x%] (
 call echo %x%. %%App[%x%]%%
 goto MenuLoop
)
echo.

:: Prompt User for Choice
:Prompt
set "Input="
set /p "Input=Select configuration:"

:: Validate Input [Remove Special Characters]
if not defined Input goto Prompt
set "Input=%Input:"=%"
set "Input=%Input:^=%"
set "Input=%Input:<=%"
set "Input=%Input:>=%"
set "Input=%Input:&=%"
set "Input=%Input:|=%"
set "Input=%Input:(=%"
set "Input=%Input:)=%"
:: Equals are not allowed in variable names
set "Input=%Input:^==%"
call :Validate %Input%

:: Process Input
call :Process %Input%
goto End


:Validate
set "Next=%2"
if not defined App[%1] (
 set "Message=Invalid Input: %1"
 goto Menu
)
if defined Next shift & goto Validate
goto :eof


:Process
set "Next=%2"
call set "App=%%App[%1]%%"

:: Run Installations
:: Specify all of the installations for each app.
:: Step 2. Match on the application names and perform the installation for each
if "%App%" EQU "Creo for company A" goto AppA
if "%App%" EQU "Creo for company B" goto AppB

:: Prevent the command from being processed twice if listed twice.
set "App[%1]="
if defined Next shift & goto Process
goto :eof


:AppA
echo Running Creo configured for Company A
copy company_a.sup "C:\ptc\creo4\Creo 4.0\M150\Common Files\text\config.sup"
"C:\ptc\creo4\Creo 4.0\M150\Parametric\bin\parametric.exe"
goto End

:AppB
echo Running Creo configured for Company B
copy company_b.sup "C:\ptc\creo4\Creo 4.0\M150\Common Files\text\config.sup"
"C:\ptc\creo4\Creo 4.0\M150\Parametric\bin\parametric.exe"
goto End

:End
endlocal
pause >nul

Paste the above code into a text editor, adapt to your situation (your specific installation and where the your .sup files are kept) and save to a file with CMD  extension.  If you save this file to your Desktop, then you can just double-click on it and then be presented with the menu.

If you don't know about what I'm saying, then you have to read up on scripting - or go seek help elsewhere in your organization as this is basic stuff your CAD administrator should be able to do for you...
