Do I need to have the OG fabrics gamepass in order to use the upload custom fabrics one?

Title is pretty self explanatory. If I don’t need the original gamepass, would it be more worth it in the long run to only buy the custom one and just upload all of my fabrics instead of just using the other pass? The custom fabric pass sounds objectively better than the OG one (even if it takes a little more work to use), so I was wondering if there’s any downside to buying it over the other one.
