Grouped Grouped or Power Frameworks

[technoshaman]

I was wandering is there a way to do Grouped Grouped or Power Frameworks (like from Hero System): schemes for providing a larger number of powers to a character for a given cost? These power frameworks reduce the cost either by requiring the group of powers to have a common theme as in an Elemental Control Framework, or by limiting the number of powers that can be active at one time with a Multipower Framework.
