There's not a built in way that's really easy and fun to use.

However, you *can* hide things if you'd like to, in the same way that components of meta-traits are usually hidden.

You must manually edit the traits, and add the tag hide(yes) to them. This will generally prevent them from appearing in GCA, but you can still see them by using Show > Hidden in each of the Character lists where you've hidden them. That way, you can find them to un-hide them again later.

So, as I said, not really easy and fun, but certainly doable.

As an alternative, or additional option, you could create a Parent item for the things you want to hide, and then ignore that block, or just hide(yes) the parent to hide the entire group at once. A bit less work if you want to hide a lot of traits, since making children is easier than adding lots of new tags.
