Synchronizing Programs Between Robots

Has anyone developed a good method to synchronize programs between robots in a cell which has parallel stations, all performing the same tasks?

I have a robot cell where there are four stations, each need the same programs to perform the same jobs.

Transferring programs is easy enough using an FTP Client like FileZilla, but it is complicated when each station needs a unique installation file. In my case, the moves in the programs are in reference to a feature that can vary slightly between stations due to minor differences in the physical environment.

I have attempted to transfer programs from one robot to another, but the difference in the installation requires a resave of the program.

Has anyone mastered this or similar process of managing a fleet of parallel robots?
