For example if you made one called "release date" and no one knew. Is there a way so it won't appear unless answered?

Also can you make the check box a multi-value?

I ask because let's say you made something in the catalog that could go under multiple sections you could check box everything it suits. When making a new field for each check box it's a tad long and messy compared to just having them all in the same section to choose from.
