not really...

To get the diff file of your PR: 

An example of a check that you can run on the PR file:
cat pullreq.diff | sed -E -n -e 's,\+\+\+ b/packages/[^/]*/([^/]*)/.*,\1,p' | sort -u > tobuild.txt

And use the matrix thing to decide which test is optional or not.

The hard part is not the integration with the CI. If you manage to write simple bash scripts which parse the output of `git log` (or whatever diff file that you provide), plugging that into the CI is very easy and I can help doing it.
