organizing plug-ins

I have upgraded from Wavelab 6 to 8.5

In v6 I was able to add my own folders in order to organize the plugins that i use most often.

In v8.5 it seems that I can choose favorites but not organize the most used (favorite) plugins into a separate folder structure with new folders that i create.

I’ve looked through the manual but can’t find a solution.Am I missing something?

I think the only way is custom categories.
