I too concur with the fact that Transition lenses won't swap quickly between dark and light.
If you want to keep eyepro on, then you'll need to just "deal" with swapping at the LCC between your sunglasses and your clear lenses.
If you wear the strap for your dark lenses under your bucket you can just yank them down and let them hang out since they won't be going anywhere. Or, have a "various BS pouch" and wear your dark lenses with earpieces.
I used one of these:

and it was easy enough to unsnap, put my dark lenses earpieces down, close the flap and re-secure. My clear lenses would sit in the same spot.
