hmm... I don't think that would be all that hard actually. I'll have to give it some consideration.I would go with all as much better than only capture "first". It will be far to tedious otherwise.
If you are going to have a tag for how many can be captured then OK no problem as long as you cater for stack attacks where a number of units are attacking/moving to that plot at the same time so each captures as many as it can.
