Custom Entity from Main Entity Workflow

Hi All,

Is it possible to create an instance of a Custom Entity using the workflow of a Main Entity?

We have a custom Project entity, and we would like to be able to create a project from a case.

In much the same was as you can create an opportunity from a case and vice versa.

I'm sure I could probably do this using stored procedures and and the ExecuteSQL action but I was just wondering if there was an easier way.

Thanks,

Gerry.
