Ive heard that you could design your gun exemple: colour,camo, is it true?

You can choose from a range of camos/colours but I heard nothing about designing your own camo.

the only thing that i have heard about camos is the skins you get for preordering, in all the vids the guns look the same (disregarding the faction difference, obiously the resistance gun will look different than the security) but everytime i saw the one AR (dont know the name) on the resistance it always looks the same, i hope there are different ones that you can unlock and with all the customization i doubt that was overlooked, but as to my knowledge nothing besides the preorder skins have been confirmed. if im wrong just tell me and provide a link so that i may learnnnnnnn
