Having the ability to create one package type and be able to sell that same package with a different duration and/or invoice amount.

Right now I am currently having to create new products each time because either the next client we sell has a different duration than the previous client OR they put more cash down up front to have a lower monthly payment. Instead of being able to sell one (Hybrid package) and set terms and pricing accordingly, I am having to create new products, price points and terms. Very hectic
