Transferring polypaint on a layer

[system]

Hey guys,
I can’t figure this one out but I maybe it’s possible.

I started polypainting my model without any layers but then I decided that I want everything on layers…so I would like to transfer the polypaint I have so far on a layer and then keep adding details on a new layer. I tried storing a morph target and projecting it on a layer…made perfect sense to me but it doesn’t work in practice

Any ideas?

make a new layer and start painting on it.

simple as that, huh?
How does that solve my problem?
I want polypaint that isn’t on any layer to go on a layer.

you can’t transfer non layers into layers.
