Vacuum/boost gauge on roots

Is there a vacuum circuit you can make with a one way valve and Tee, to get accurate vacuum readings along with boost? I want to get rid of the separate gauges.

I did a search, did not find much. If you could mix the manifold signal from the carb base, and the boost port from the blower housing, it could work.

The impeller turning scatters the vacuum signal.

How do you roots blown guys run a single vac/boost gauge?
