Request: improve Xhotbar for pets

[Nicobo]

There's an option in Character Settings for whether to use the Pet Crossbar or not. What I (and many players) do is turn off the Pet Crossbar, and place the pet commands on one of the regular crosshotbars instead. That way you can arrange them as you like.

I want to use the preset ExHotBar because the action buttons will change to the corresponding pet-commands dynamically.
I just don't understand why [dismiss] will put on R2+O which is the most frequently used button, usually assigned to the most frequently used ability ^^;
