Can we get more options for viewing our allies camera in game?

Something I have been personally been trying to improve on in my league performance recently is looking at what my allies are doing. However I feel like the options we have are quite limiting.

One of the things that particularly confuses me is having set buttons for ally 1, ally 2, ally 3 etc. As someone who is most definitely not an ex starcraft pro, reaching for the f-keys as well as remembering which of my teammates is which can petty difficult without having to revert to the full double-chin-tuck-look-at-the-keyboard-and-type-with-only-with-index-fingers manoeuvre. Either that or I end up malph ulting the wolf camp when I try maintain eye contact with the screen.

It would be nice if we could bind the keys to a particular ally easily at the beginning of the game, similar to how the hotkeys for abilities are now. It would be much easier for me to remember if i could always have f1 as my top laner, f2 as mid, so-on etc.

I would also like an option so that you can temporarily lock the camera on an ally, either by holding the button down, or just by default when you press it.

Finally having a binding which rotates between your allies' views could be much more keyboard economic; press the key once to switch to ally 1, twice for 2... 5 times to switch back to yourself. That way you can just keep pressing it till you get the view you want.
