Specifying accepted collisions for the dependencyconvergence rules

Hi all,

I ran dependencyconvergence rule (of the maven-enforcer-plugin 1.3.1 pluging) on my huge multi module project and got a very large report specifying a lot of dependency collisions (there's a surprise! ;-))
On the one hand, it will take a lot of time to align all the dependencies, on the other hand I want the CI build to start failing only on new problems.

I did not find a way to specify exclusions for the dependencyconvergence rule. Is there such a feature at all?

Thanks,
Vitaliy
