While we now do add questions to the reopen queue in response to 3rd-party editsin response to 3rd-party edits, we ignore those where the editor has given some indication that he doesn't want the post reopened (voting to delete and flagging are pretty strong indicators here, so that's what we go with). An explicit checkbox clutters the UI with what should be a boring implementation detail, so we're not going to do that.
If you're making a lot of edits on posts that are closed - nominated for deletion - but which you explicitly do not want to see reopened... Then perhaps consider spending a bit less time rearranging deck chairs on the Titanic and instead putting that time and effort into other, more constructive activities.
