Reload mortars under the repair task

[Freya 'Tail' Fairwing]

Something I just thought of while managing a colonist as he reloaded all six of my mortars after a fight, it could be good for the reloading of mortars to be done automatically by colonists set to repair, maybe after everything that is actually damaged is repaired. Manually reloading them with drafted colonists is something I can see going horribly wrong one day, leaving someone staring at a mortar until their stomach eats itself in hunger.
