Opportunity (Deal) - Related List Zoho CRM

Opportunity (Deal) - Related List Zoho CRM

I've been able to create the desired Related list and associate them to an Opportunity (Deal).  However, I only get the Assign button.  I've added the Quote module and a custom module.  I would like to be able to add/create a new Quote from the Opportunity (Deal).  How can I set this up?
