Strange behavior with Group Tracks

If the signal flow is Track > Reverb > Master Group A, then you cannot go back to Reverb because you are creating a feedback loop with the Reverb’s input.

On a side note I wish it could do that, so that we could use Waves’ Q Clone and analyze every Plug in’s EQ curve; we can only do it physically with cables.
Protools and a few other DAWs can do that.
