Shipping method - dropdown list for multiple stores (in-store pick up)

Hi everyone,

I have a question concerning the shipping method page. I was wondering if it's possible to bundle all of my 15 stores in one shipping method with an dropdown list? Now i have 17 shipping methods in total and my page is way to long with the radio buttons. I've created a shipping method for every store (fixed rate). This is what i want to accomplish:

* send by mail
* send by international mail
* in-store pickup
      - store 1
      - store 2
      - store 3
      - store 4
      - ....

Kind Regards
