Dynamic forms

I am wanting to create a master form with sub forms inside it.  When a user checks a box for the corresponding sub form it will populate into the master.

I have multiple agreements for different services my company offers.  Not all cusotmers want all the services so we are trying to streamline the process.  Most of the agreements need the same information about the customer.  I'm hoping that I can create a master form that collects the necessary information, and allows the user to select the services the customer is wanting.  When a service is selected the corresponding service agreement will be populated with the necessary information, and allow the user to print just those agreements for the services the customer is requesting. 

Does that make sense?
