I am building a simple project management application and have run into a problem.

Background:

My application consists of 4 "objects". These objects are: Projects, Activities, Employees and Roles.

Every project consists of several activities and every activity has several roles. Each role is connected to a employee.

I want the application to have 2 "tabs", "Projects" and "Employees".

The problem:

The activities are created within the "project form" in a subform. I want to create the roles while I create the activities. Is it possible to add a subform to a subform? If not, can I do it in an other way?
