Helmet insignias/symbol need to be seperate in the helmet customization

i think its a insignia but it also be a symbol not sure.

So with the helmets we can change them but the insignias/symbol (the icon in the middle of the helmet)
we cant without changing the helmet, all i wanted to do was put the deathwatch helmet insignia on the MARK X TACTICUS helmet with the hood but i cant becuse the death watch insignia is tied to the standed helmet.
Is there anyway we can make the insignias on helmets changebale to what we want becuse there are some good helmets to use  but most have the default Skull yet i want to put other insignis in that place. kinda surpise this wasnt done at the start. as theres many insignias but most are only on the default helmet.
The insignia needs to be its own armour slot card like the other armour piece and have all the current insignias availible.
Another example: Liuetenant helmet has the defualt insignia icon which is the skull, its the only helmet that has the liuetenant color scheme but i want to put the ultramarine insignia in its place but i cant as stated berfore, its tied to the defualt helmet.
