Is your feature request related to a problem? Please describe.
With the mouse, you can grab a stack with your cursor in a container and drag left click to evenly distribute the items, or drag right click to distribute 1 item to each slot. This functionality is missing with controller support.

Describe the solution you'd like
Holding VMouse LClick and VMouse RClick buttons should act the way they do with the actual mouse with distributing items in the container gui

Seems to be implemented in the 1.21 version
