[2022] Breaching Shotgun Reloading One At A Time

Is there anyway to fully reload the breaching shotgun at the moment with a single press? Seems to only reload a single shell at a time and the animation takes an eternity to cycle so you can begin the next one (same problem I have with single shell reload on regular guns)

Wouldn't be so bad if you could mash the R key a few times and they'd put in that many shells but it sure kills momentum when you have to stand for 10 seconds waiting.
