Create future potential upon closed won of existing potential

Create future potential upon closed won of existing potential

We have the need to follow up and win a potential for an account on a monthly or quarterly basis. Essentially, there should always be at least one open potential for an account ,under certain criteria. What I would like to do for starters is to create a new potential for an account of an existing potential when this open potential is marked "Closed Won". Could someone point me in the right direction, please? Thanks in advance, Dustin
