Using the text file option for assigning a CBSubs plan is just not user friendly for customers.
I understand the CBSubs Import from text file process completely and that assigning subscriptions to members is a one-time initialization event, but it's the customer who I'm concerned about that will need to be assigning user records (that have been imported via CBJuice that don't have a CBSubs plan yet) and the import from text file is simply not user friendly for these end user customers.
There just needs to be an easier option to assign user records to a CBSubs plan, hopefully this CBSubs usability improvement will be added to CBSubs soon.
