I wish to know a way to have all the pre-made faces in CAS. e.g. if I download "John Joe" and "John Smith" and 15 other face presets I can't tell apart which combo of which nose/chin/eye shape would make John Doe's entire look and I sit with a bunch of unnamed noses and chins and eyes that I have no idea what to do with.

Furthermore, I really love the mermaid premade faces from the game [not cc] but can't apply to other species/races. I have managed by having mermaid with face preset #xx<3 to have a baby with otherraceXX until I get random with the mermaid-face but the otherraceXX race e.g. spellcaster with the mermaid face. I would like to inquire if there is a way to make all the face presets for the whole entire face show up in CAS.

I have included a crude diagram :

so question 1: is it possible to add an entire selectable face preset from cc - or even from my own previously saved sims. the entire face with all the parts.
question 2: is it possible to add sims 4 non-cc faces that are already in CAS but only available to certain creatures to all creatures e.g. mermaid premade looks [face] to spellcaster premade face options?
