Auto incrementing diagram names

As it is often unimportant which name a diagram has and more useful to just create a new diagram on a page with a single click. It would be useful with the ability to simply click the macro and have a new diagam ready to edit. For this reason an auto-incrementing name feature would be nice.

This way it would still be possible to edit it to change the reference later if a pre-existing diagram is needed, but since it's most common to create a new diagram, it would be more efficient to be able to forego the pop-up when inserting.
