Yeah, figured it wouldn’t take long before that was requested, haha.
Thing is, I don’t know how to do this 
The current plugin is a pretty straightforward modification of the excellent plugin tutorial by @eviltrout
I don’t know how to create an “add icon” button that spawns multiple fields; I know it can be done, since the navigation plugin does so, but I’m pretty new at this and I just created this one out of a personal need and to learn.
I might take a crack at this during a weekend somewhere, until then… PRs are welcomed
