So,I decided to add some "Creative License" to my FNV armors,but I've got problem,the specific armor I'm trying to edit,is an .esp activated retex,with the .dds files contained in a .bsa,and I haven't the slightest idea how to add a file to a .bsa,I can extract the files just fine though. So yeah,I can't just extract the .bsa,because it needs to be in a .bsa for the retexture to work,and I don't have any software that I know can add files into a .bsa
