Hey, if I'm reading it right with what you're asking, I think this feature has always existed. I think this is the settings you're looking for: https://eu.finalfantasyxiv.com/uigui...switching.html

When you enable customization, you can shut off the (Cross) "Hotbar" by deselecting them. Thought I think this setting should have been under Cross Horbar settings instead of Custom.

There's 2 ways to cycle, either when the weapon is sheathed or pulled out. If you disable 2 through 4 a keep the rest active while weapon is sheathed, then rotating through tapping R1/RB would cycle through 1, 5, 6, 7 and 8.

If you uncheck 5 through 9 for unsheathed, then R1/RB will cycle only through 1 through 4, which would probably have all combat focussed actions.

I hope this helped.
