Print Organizer Print set refresh/reload

Hello all.
It would appear that if a dgn has been added to the print set, and a fixed definition is being used, that any additional boundary elements added afterwards will not be picked up w/o reattaching the dgn.
If  utilizing the variable definition I see that the additional boundary shapes do create additional sheet output during the print process as intended.
Understanding all of this, my question is whether the ability exists to "refresh" the selected files from the print set when using a fixed definition w/o deleting and re-adding?
When processing cross section files that contain many boundaries (not separate models), the inability to have Print org catch added borders and display them in the list view impairs the ability to sort or apply individual settings.

Thanks,

Mike
