Units don't clear nests automatically

[EmeraldViper]

This one might be a tough request, but aliens can be useful if their nests are inside your borders. Your workers or explorers, or other automated units, may clear them by accident if no alien is guarding their nest.
So, would it be possible to add an "action button" available to units in empty nests so one can choose to clear them or not? (would the AI understand the change?)
