Add the ability to require fixed-length fields, not just variable length fields
We require certain information to create a library card, however Sierra does not enforce this requirement at the system level. Since it isn't mandatory, some data simply never gets captured and creates more work on the backend.
Beyond that, having certain information in the record would allow us to build a better understanding of our usership so that we can make better decisions as an organization.
I especially would love the ability to require any and all of the fixed-length fields; especially patron category, birthdate, home library, and notice preference.
