FR: Merge mono to stereo tracks (and vice versa)

My personal problem:
I want to use immediately and automatically without effort STEREO-Insert-FX on MONO-Channels(WAVs)!
e.g. recorded Monoguitar with Stereo-Phaser, Snare with Stereo-Delay, or Vocal with Stereo-Hallroom, or a Synth with Chorus blabla etc.)
Or: mono fx directly on stereo-wavs (!)

→ W-I-T-H-O-U-T dragging (mono)regions to newly created stereo-tracks!

Why we not can have only (!) stereo channels? switchabel to mono (on demand)?



And:
I want to edit ONE side of a stereo-WAV in the cubase audio window!

I want a “STEREO → L/R MONO” (Split Stereo, ProTools etc.)
and a “L/R SPLIT → STEREO” convert tool in cubase!
