Option to create a tag when bulk assigning

We are re-organizing a bunch of existing posts and some require new tags to be created. We noticed that when we are trying to reassign tags we don’t have the option to create a new tag. Compare that to I am creating a topic and assigning tags, I have the option to create a new tag. It would be very handy to be able to create tags while bulk appending tags.
