Assistance - Shapes

Im new to Prezi and would appreciate some help please.

Assume I create a new template - blank. For the next slide I use for example a square box shape.
Call that slide 2.
Inside Slide 2 I wish to create a Sub-Topic which I do. It defaults to same square box.
What if I did not want square box but round box in that specific slide?
When I change it to round it auto changes all of them.
So how does one insert a shape (know how to do that) but then make that shape the actual layer that takes you to Sub-Topic
