Being Able To Toss Back Already Thrown Frags ?

@JACKTH3R1PP3R97 I wanted them to be thrown back, but I don't see it being plausible to deploy due to the explosion timer, finding the grenade most of the time when it lands, etc.

I rather see the ability to stop ones you thrown (like if you accidently threw an arc), except thermites since there's no point undoing that mistake.
