Multiple physics layers in Godot 4.0 Tilemap?

Question

I am loving the new tile map system in Godot 4, but I have a question regarding the physics shape of the tiles.

It seems like each tile can have multiple physics layer shapes, which would make implementing more complex behaviour easier, but the editors only offers one layer.

The new tileset editor introduces the concept of Tileset Layers. A tileset layer is simply a way to add a set of properties assigned to each tile.
All tileset layers are optionally added to a tileset, each added layer provides a single feature to the tileset. For example, adding a "Tilset collision layer" to a tileset allows it to handle collisions.
Occlusion or navigation have also their dedicated tileset layers.
