option to turn off Proximity Grenade

[LuckyClover]

Proximity Grenade should have option to turn them off and reuse-I dont like destroying them when I need to go in place they were throwed-
for example when I used them to block doors I often need to go in at some point-it would be great if they would have some kind of remote

Proxy grenades are the thinking mans grenades.
that said, i think i lost about 5 soldiers to my own grenades in my current game.
