5.6 Metahuman Character Creator Lacks Roughness texture override

I customised a metahuman character who has no nose but when I go to override the textures I find no option for roughness, hence the shiny part of the face where the nose would have been.
It would be great to be able to override roughness too so I don’t have this issue.
If there’s a workaround, please share. There must be a roughness texture somewhere.
Thanks in advance
