Make multiple non-transformed collision shapes in a StaticBody get discarded in engine's broad phase algorithm

[baz-atak]

According to documentation

When using a single non-transformed collision shape in a StaticBody, the engine's broad phase algorithm can discard inactive PhysicsBodies. The narrow phase will then only have to take into account the active bodies' shapes. If a StaticBody has many collision shapes, the broad phase will fail. The narrow phase, which is slower, must then perform a collision check against each shape.

It's likely that these colliders are in close(ish) proximity to one another, therefore why not generate a single shape that encloses all the given colliders, then use this to determine if all those colliders can be discarded before testing each individually? e.g. a sphere or a box - perhaps based on which generates the smaller volume for the specific layout of the original colliders.

For instance I could then create a room consisting of simple box colliders for the walls with cut-outs for doors and windows etc., and save on multiple collision tests in the background.
