Diesel glow plug switch

I recently read an article advising diesel owners to "double start" on cold mornings. "Double starting" means to turn the key to 'ON' so that the glow plugs come on for 1-3 seconds, then back to 'OFF' and immediately 'ON' again, only then to start the engine. This is supposed to double the amount of cylinder preheating by the glow plugs.

This got me thinking whether to hack a switch to manually turn on the glow plug relay, allowing me to do the same (or more generally, to better control how much longer the glow plugs work) without fumbling with the key in the ignition.
This should be a momentary switch/button, so there is no risk that the plugs stay on by accident.

Any opinions?
