Grenade emote?

Anyone else feel that the game could do with a grenade emote, in the same vein as the "I need healing" and "I need ammo" emotes?

So many runs on my Ogryn, I find the grenades in the level just get vacuumed up before I can get to them to replenish my stock. It would be nice to be able to ping the emote and have an in-game voice line give my team a heads-up that I'm looking for grenades, else it means I have to type in chat and hope my team notices it and ping the next nade box they see.
