Hunter set focus on pet

If I set focus on my pet and then mount up on anything, when I dismount I have to reset focus. This is a real bother, especially in immediate close encounter situations. Please consider making the set focus stick until changed manually or pet dies such as for warlock pets with soul link. Thank you.
You want the General Forums. Developers, who could implement this change, do NOT read this forum.
Why do you need to focus your pet? There's a target=pet or @pet you can use in macros instead.

For instance, here's my hunter's Misdirect macro:

#showtooltip Misdirection
/clearfocus [btn:2]
/stopmacro [btn:2]
/focus [help]
/cast [target=focus,exists,nodead] [target=pet,exists,nodead] Misdirection

With this sort of setup, you don't need to constantly waste time setting focus to your pet. It will automatically use your pet as the target if you don't have a focus. So in instances you can target the tank and hit it the first time to set focus and cast it, but solo it'll auto-cast on the pet.
Thank you both for your help and especially for the macro, Feylan. I will set that up and hopefully it will solve this issue. Thanks again.
