Activatable repair speed boost

Lert: There are those times where you're tracked in the open, or your turret ring is knocked out or your engine gone, but you've already burned your repair kit. The only option in that case is to just sit it out and hope your crew can get the module up and functioning again before you get horribly murdered. With some modules on some tanks this can take a relatively very long time.   What I propose is a button that can activate a repair speed boost on the crew, in exchange for a temporary reduction in their own functionality.   Activating this function would, for example:   - Add 50% to your repair speed (so you repair at 150%, stacks with toolbox bonus) - Halve your vision range - Halve your reload speed - Halve your radiorange   ... for the duration of the repair.   The reasoning behind this is that sometimes the thing you care about most is getting your repair done as quickly as possible, and your button press would tell the crew to concentrate all effort on the repairs, instead of doing their actual jobs which somehow magically the crew is still able to do while you're repairing a track or turret ring in the current system. Ofcourse, after the crew is finished repairing, they will go back to doing their own job again so your reload speed and vision and radio ranges will return to normal right away.
