A limited set of actions can assigned via macro commands. Incompatible actions are ommited from the generated macro. Also note that Macros are limited to 15 lines each.
This hotbar is pulled from Gingergaming's channel and is used for myself with some modifications to remove macro usage.
AST as of 6.4
Waiting for the new action images to get added in to fully get this good
Make sure to change Double tap L2 to "Cross Hotbar 4 - Left" and Double tap R2 to "Cross Hotbar 4 - Right"

The XHB setup I use for my Astrologian. 1-3 are unique to AST, all else are shared between all jobs. XHB4's LT->RT pane is a selection of emotes. XHB7 is my job selector.
