Quote - I know exactly what you went through.  Glad to have made a difference. 

You could make your adjustments in the VSS prop and resave it into your library under a unique name.  Although you will accumulate several custom props that way, it is perhaps the best way until the general version becomes available.

That’s what I’m doing. I also tend to save finished figures to my library as well just in case they are useful in the future. That way, I know I have a reference to go back to.

I’m very impressed by what VSS’s shaders can do - I could lose hours to it. Maybe it needs a health warning!
