I would like to be able to create templates for Estimates and Invoices. I am NOT talking about email templates which are sent based on an existing invoice or estimate.
Use case: create a true Estimate_Template which contains a pre-populated large number of user-defined SKUs. I click "New Estimate from Template", which opens a new Estimate with the pre-populated SKUs, which I can then delete items, edit qty & prices before validating & sending.
This will cut down on admin for me creating new estimates based on similar (but not identical) system sales and projects.
