I have a 100 original themes and create websites for clients. Instead of uploading a chosen theme to each site, is it possible to put them in say "http://example.com/themes" directory then in
WP site #1: Browse and install theme from the above directory
WP site #2: Browse and install theme from the above directory
WP site #3: Browse and install theme from the above directory
etc.?
Or can i only browse and choose themes that are in each sites theme folder?
