If you're one of those scholars that wants to control your both pet, and have the pet actions dragged to hotbar, setting up a macro to change the content of a hotbar might make things easier. But this requires you to have 2 unused hotbars
I.e hotbar #5 and #6

/micon "Summon"
/ac "Summon" <me>
/hotbar copy SCH 5 SCH 1

And other with "Summon II" and 5 is replaced with 6

It copies the content of your hidden hotbar ( 5 and 6 for example) to the visible hotbar 1 that you have keybinded. Use for example hotbar 5 for eos' and hotbar 6 for selene's skills.
This is really helpful especially if you have pet actions on 1 hotbar like me.

Set the hidden hotbars as if it was the #1 hotbar.

Yoy could use this witj CS too, but then you'd need 2 macros, as you'd want one macro to change the hotbars to attack mode, and other to change back to healing mode.

Sorry if that's a bit hard to understand. I know that I'm mostly bad at explaining.
