I'm all for SE providing more options for players like this even though I wouldn't use this particular option.

May I suggest a workaround that you may or may not like? I've set all the "main menu" options that I want access to frequently on-the-go to one of my cross-hotbars, in particular my WXHB, the one where I double press one of the triggers to bring it up, but if you are already using both your WXHB and expanded hold XHBs, then consider the following in the next paragraph.

Go to Character Configuration -> Hotbar Settings -> Custom -> Set Selection and enable all 3 options in that section, and in the unsheathed section select only your main hotbar you never want to leave while in combat. Then for the sheathed section, select only your main hotbar and the hotbar you dump your main menu shortcuts to.

With the previously stated configuration settings, you should be able to initiate auto-run, presumably your weapon is sheathed at this point, and then just tap R1/RB on the controller to swap between your main hotbar and your main menu hotbar.
