Please change element selection mode to keep level lock.
What i mean - i want to select for example "shapes" I have Level locked so it should select only "shapes" on this level - not all shapes on every levels ( maybe just ad small lock icon to element selection or just keep lock )
I am not understanding what are you meaning to. In Drawing Aids -> Locks -> turn on Level Lock is working as what you are describing. You can call that tool box out.
