Reverse Step filtering in Dev. studio

Would it be possible to have an option to reverse the step filtering? Ie. to have the filters be inclusion instead of exclusion filters?

I am unsure about the normal case in enterprise development but in our case at least all packages are prefixed dk.telenor.*
It would be very useful if it where possible to specify just one debugging step filter (ie. include dk.telenor packages).

Workaround is to add all possible packages, select all then un-select the ones you are interested in.
