Adding Capex to an exiting application

We are using Hyperion Planning 11.1.2.4.005 - We originally deployed our Planning application with the 3 generic plan types (Plan Type 1, Plan type 2....). We used a classic planning deployment. Now we are in need to deploy Capex. Question - is it possible to add the Capex to our existing application using Add Plan type or other means?

Please advice
