Incompatible packages - more comparison selections

In VI Package Builder I'd like to be able to specify a less-than-or-equal package version in the Incompatible Packages section.

The use case is this:

I update a low-level reuse VIP A, breaking compatibility with some of the VIPs that depend on A. Currently (VIPM 2013), in A, I can only select Incompatible Packages with versions "greater-than-or-equal", or "equal". What I'd like is for the VIP A installer to tell the user that they must upgrade their already installed VIP B, that depends on A, if they want to proceed with upgrading A. To do that I need to be able to specify package B from a version downwards as an Incompatible Package in package A.

Makes sense?

Cheers,
