Potential Details - create and add a custom details list

Potential Details - create and add a custom details list

Is it possible to create a custom details list on the Potentials' page?
It would be dynamically populated in the same way as other lists ASSOCIATED with a Potential: Contacts, Attachments, Notes etc. Every time I would want to add a new detail I would click 'New' in my custom details list (on the Potential page) and add a new detail (based on defined field structure).

How do I do it?
(a) from within CRM
(b) can I add a custom-made database created in Zoho Creator to Zoho CRM Potential Details
???

Thank you.
