Is there a way to transfer a program from STN1 work object to STN2 work object?

Skittles

We have an ABB IRC5 2600ID welding robot with 2 back-to-back headstock/tailstock stations.

My question is how would I go about copy and transfer of program that was written on STN1 work object and get it to "convert" over to STN2 work object? Let it be noted that I do not have RobotStudio, neither free or licensed software version. I am looking for any potential ways of doing this out on the real controller. I read a code routine called MoveExChange that was posted somewhere.  It seems to use CalcT . . . or something of that nature. I have never dealt with that type of coding and wasn't sure if it applied to what I'm looking for.

On my laptop, I did copy the part program module I want to transfer and I edited any tags or labels for STN1 into STN2 in notepad.  This loaded fine into my controller, but obviously doesn't translate positions to the other work object properly without errors or still trying to go to STN1.

Any help or insight is appreciated.
