Pet summoning

I'm sure this has been commented on, and I apologize if it has. I find it very annoying to have to constantly summon my pet after using a mount. There is no way to press heel while on the mount to prevent the pet from attacking whatever attacked you. I do use the steady button before mounting, and it still ends up "withdrawing." If not the availability of the "down, pet" buttons, make it so that it temporarily disappears while you're on the mount. Something to prevent constant summoning.
