I already know that "change shape" does not work outside of the "original" shape tools which is insanely stupid!
So I am looking for another way to do this.
I have created a huge "mind map" but I didn't use the "mind map shapes" from the library and I want to change all my items to "mind map" without having to completely re-build my layout which will take weeks since the entire layout I have created contains hundreds of items.
Can I export the layout and then import it again but using"mind map" shapes?
Can you (LucidChart) do some magic on the back-end to update the layout for me?
