Stamp Deletion Brush

Would be pretty sweet to have a brush that you can use to run over the map, specifically whatever layer you wish as well, and it deletes stamps that are placed.

Ex. You broad stroke an entire area with trees but realize you want to remove some for lets say a river, a lake or some other use. You can select a brush under the stamp options and swath delete wherever you want.

Try making a huge forest and then deleting a few trees or one at a time to make a river going through it. Its incredibly time consuming and rather tedious.
