Some questions about mesh resolution selectableLOD levels.

I noticed that Michael 4 has some selectable LOD levels which I'm sure I'll find useful for some games I plan to program and I was wondering if genesis 1, genesis 2 and genesis 3 non essential characters will have the same LOD selectable LOD levels. Right now I only have the essential genesis 1, 2 and 3 characters and none of them have them. I'm about to buy Gianni 6, Gianni 7 along with Cole and Gray for Gianni 7 and I was wondering if they have selectable LOD levels like Michael 4 has. If they don't have them, is there any add-on to add them?

Thanks for reading my post and have a wonderful day!
