Spitballing new voice emotes

So I was thinking, I love how robust the voice wheel is, and how much you can actually communicate with it, but I'm realizing that it doesn't cover 100% of the things I need for it to, and maybe just adding one or two things could optimize it.

Honestly, it's amazing as it is, I can even communicate complex ideas like "Should we go here? Yes, no?" by spotting something and hitting affirm or negative... and people get the idea. Or "Follow me" and spotting a clear route, people know that way is clear... ish...

I would LOVE to have a "cover me, please" emote of some sort. Can't tell you how many times I've needed just a tiny bit of breathing room and being able to get a squaddie to suppress while I load my RR up and fire again would be amazing! Most people know to cover, but even so, maybe they're not looking at you when you need it, ya know?

And now with multi-crew vehicles, perhaps spotting the vehicle could indicate "I need a ride!" to the driver? Just something to make it a little easier to grab that rear gun and do work.

I'm sure other people have ideas that I may not have thought of too?
