In the customize support structure dialog, there is a way of deleting automatically inserted supports, which is very convenient if you have only a few supports to remove, for instance when small horizontal holes don't need it and you want to avoid removing them manually after printing.
Would be really useful to select more than one at time, removing a slightly long hole can take minutes clicking many times on the same place.
A selection box should be great for instance, with the traditional Shit+click for adding deleting selection.
Possible?
