Using scene editor to edit stored data

Hi!

I'm creating a puzzle game with Unity and I would like to know if it is posible to use scene editor to edit level configuration (board, goals, etc), so I don't need to create a scene per level.

My idea is to pick a level at gameplay scene (while edditing), change rows, columns, gems, etc, configuration and be able to save it. Is that posible? (I know I can create an "editor" scene to save changes and so in a JSON, config file or whatever, but I'm looking for the other solution).

I'm a completely newbie at Unity Editor.

Thanks a lot!
