Custom fields should be available for Views and Reports.
My specific use case is around bills. Different vendors have different preferred payment types (checks, credit cards, ACH transfer, etc.).
I can add a custom field for each vendor for "Preferred Payment Type". I can do the same for bills. I can have the bill field populate from the vendor field via custom function.
What I can't do is use that information in any way. I'd like to construct a view for each payment type, so users can then pay all of the bills by check necessary, etc. Without being able to construct a view, it's not really helpful.
Thanks for the consideration.
