What bothers me most is the need to go trough the engineering for every single module.
Imho once a module has been engineered the same mod should be extended to other same modules. For example once the FSD size 5 has been mod to grade 5 (not less) I should be able to apply the same mood to any other FSD 5 size without the need to go to an engineer or pinning the blue print and it should require the materials for a single roll of grade 5.
This mod should also cover all smaller FSD but not the bigger ones. For example the mod of a thruster 5A should cover all 5, 4, 3 and so on but not the 6 size.
