Option to have reverb (or other future effects) in mono mode

[baconmonsta]

I use Minidexed as 2 synth engines TG1 & TG2" panned hard left and right. The output channels (left & right) go to different destinations in my music setup. If I use reverb on either of the engines, the reverberated sound will start leaking out from the other channel as well, rendering it useless for my use case.

Therefore I'd propose having the option to set reverb into mono-mode (i.e. no stereo widening) to keep the stereo image clean.
