Now that we have the ability to create custom slips in Koha, I'm wondering if we could add some functionality where we could create a custom variable in the template, and when we go to print the slip, Koha would prompt for values for those variables. An example would be, we have a very simplified curbside slip we use, and before the slip prints, we might want to enter in parking information, or some notes, that would be included on the slip.
