You can only do it if your character has access to that ability from within the game.

On a technical side though, all that data is stored in the character data files on your computer. I've previously copied them from one character to another to duplicate my HUD settings, macros, etc. So if you or a friend had a character with everything to 60 and that friend put every skill on a hotbar, you could overwrite your character's with that and adjust, but it's not really worth the hassle. PotD is a much better way to go about it and then you also get exp!
