Can I make nested forms?

Is there a way to have nested forms? I may not be using the correct word, but here is what I want. If I am entering data for an organization, and I want to collect some contact information, can I call up a dedicated contact entry form from inside of the organization entry form? (And then, after selecting "Save" on the Contact form, I could continue filling out the organization form.)

why not just create a group of questions for contact information in the first form and apply a relevancy to it so that it only appears when necessary?
