I'm not sure if I get the question.
Do you want to click/touch a sprite (e.g. a button) and then switch to another layout?
At first you have to add mouse (or touch) handler to you project.
Just make a right click to your canvas and use the search on the top.
Looking in your eventsheet,
- create a new event and search for the mouse.
- There you select on click on object and select your sprite.
- add a action and select system -> go to layout
That's it
