Offering Subscriptions when Paying Dues

Hi everyone,
We are new to the iMIS Billing process - here is what we need to accomplish. When my dues are due I am charged $50 for my dues - but then I have the option to select different journal subscriptions - so for every person we would like them to have the option to select any of our journals - we are mainly concerned with accomplishing this on the Public View - any thoughts?

Thanks!
Kristin
