Multi-editing Mod Elements

If this feature already exists and is possible to do, don't hesitate to tell me

MCreator already has a multi-selecting feature, but it doesn't (to my knowledge) have a way of editing multiple mod elements at the same time. It would be so much easier and would save a lot of time. I think it would be really cool!

So instead of individually editing a ton of mod elements, I could edit all of them in some sort of collective menu.

For example, I could multi-select all of my custom blocks and change their "Creative inventory tab" at the same time.
