Enable loopback creation with correct source/sink

[nopeslide]

Great piece of software!
I use pagraphcontrol to manage multiple concurrent recordings of conferences.
When I setup a new recording I create a lot of Null Sinks and loopbacks.
Since loopbacks kinda connect anywhere on creation, they initially connect wrong source/sink pairs on full volume, which end up in the recording.

What would be really helpful if I could create loopbacks with the correct source/sink (pulseaudio is capable of this).
I imagine an option like connect to in the context menu of a source which is followed by a selection of a sink.
This would also allow to create setups faster.

here is a screenshot of one recording setup
