No answer or solution is expected.
Since you write in public forum, while you can ignore offers you can not block they appear

For automation writing:
a) N buttons (5,7,...), each set predefined Pan level directly. So you are always one button press away from desired pan position (but can not write "smooth" changes)
b) "normal" knob or fader, with bright "central" part setup for pan center
c) endless encoder with tuned for your convenience resolution
d) a+b+c, to use each when desired. For (b) to work nicely with other during the same writing session, the fader should be motorized (or "virtually" motorized, f.e. on the phone/tablet).
All variants can be done with AZ Controller and any MIDI device... gamepad... Android/Apple with TouchOSC/Lemur.
Note that AZ Controller will not work in parallel with stock plug-in for your V700 (they will clash badly), so you will need a separate device.
