The problem is, when the material
covers the hole, the vac starts working pretty hard (because the port

Any ideas on a way to add a vac pressure release somehow?

I thought of actually adding yet another hole and dust port, and some
sort of Y- or T-fitting.

I currently only have dust collection in the fence. It seems to me that
the best of both worlds would be to use a "Y" fitting and combine the
two--I can't think of a scenario where both ports would be blocked
simultaneously.
