Can the AI remount previously dismounted troops?

[hoplitis]

So an unarmed A.I. transport (i.e. a truck) after unloading the unit it carries has effectively completed its mission in the game. Wouldn't it be logical for those unarmed transports to retreat offmap ?. This would remedy somewhat the famous "OP fire draining" issue and would also give the human player less targets (somewhat more difficult game against the AI). Is this doable codewise?
