Cooking Grenades? It would be nice to be able to shorten the timer on the grenades to allow for quicker tactics.

Would it be possible to click the activate button to get the standard blue line, then hold the activate button to get a red line that starts cooking the grenade? Timer optional to show how long you have.

I feel like this might be useful for future grenades as well such as flash bangs or EMP style grenades to shut down vehicles. Having more control over them would be great.
