Purchasing a la carte

Good Morning,
I wanted to suggest an a la carte feature. Where we would get the option to purchase a design board or selection sheet per project as opposed to monthly. I personally have canceled my account as I am not doing design boards as much as I use to and have teamed up with a small custom home builder. Being able to purchase a selection sheet per project would really be beneficial to my business as I don't have monthly projects with him but I work on 1-2 project throughout the build process. Just something to think about to deliver to some other business owners!
