How-To: Create folders within "metadata schema" area
First of all, I'm using 6.5 on-prem with 6.5.21 service pack. Can anyone give me information on how I would be able to create a folder structure within the metadata schema form area? I am running multiple sites within my instance and want to be able to delegate rights for the different site administrators to be able to manage/create their own metadata schemas as needed, but only for the sites they manage. I know if I'm able to create a folder structure then I could accomplish this through folder security, but there is no out-of-the-box method to create folders within this interface. The only option under "Create" is schema form.
Even if I have to do this through a package deploy from a lower environment where I can manually create the folder structure I'd like to do it, but I can't identify the location of these schemas within the DAM.
