If you want to hide different Sketches they will have to be placed on different Planes.
Use Add > Construction Plane > choose the Offset option
Planes can live as little as 0.001mm apart.

If you want to go the Folders route see:

You will have to separate your Sketches in to separate Designs.
To do this go to the Design Thumbnails Page and Duplicate a Design having ‘different’ Sketches
Keep the Original, untouched, then delete unwanted portions of the Sketch in the Copy Design
This can be repeated with further Copies.
