Yes, it closest thing I need, didn’t know about this feature.
Usually I don’t need much shapes, so preparations after reopening document should not be tedious.
Selections I use for the restriction, but periodically, when I need to enforce shadow or highlight or something to pop-up from others in a object. All paining including them goes into one united layer – without layer separation into background, props, faces etc.
Anyway thanks to everyone, now I am sure that I not missed with hotkeys.
