Replace name mapping files in Project Suite

I have a project requirement where we need to maintain a single project suite for the execution in multiple versions of the application. The main difference between each version is the namemapping.tcNM file and changes related to the namemapped objects.

Say I have 3 versions, so I have kept 3 different namemapping.tcNM file for each. So is there any way to replace the namemapping file of the corresponding version before opening the project suite? Cannot use the merge method as there will be 'n' number of versions in the future, so manageing it all in the same file would be chaotic.

Using Jenkins to trigger the test execution. So before that need to replace the namemapping.tcNM and start the project suite. Any idea?

Thanks
