Thicknesses

Currently,the hollow parts in the game such as Inlet, their thickness is fixed 5cm. Which can save hair, but sometimes it can also cause some annoyances.
For example, if I want to change the thickness of missile caniser and the plane bulkhead and they are made of Cargo Bay without base, I can only add one more Inlet, Cargo Bay without base or complete it with fuselage splicing.
So can you guys please add the ability to change the thickness of the hollow parts.
