I always used the following pattern
_work.pbl _last_minute_changes.pbl 1.pbl 2.pbl 3.pbl ...
I export objects from 1,2,3 ... and check them in clearcase. I configured nightly builds using PowerGen to import the download into a network share. I am using a script to pull these pbl into my view. I check the object from the box and import it into my _work.pbl. Make changes, export them and check them clean. Then the trigger starts the CI assembly, which imports the object into _last_minute_changes.pbl and restores it compared to the previous pbl nights, and then archives it to a network resource.
script work.pbl. , script, sync'd pbl pbd's.
