Currently, there is an option to sort subfields for BIB records, but there is no option to sort subfields for HOLDING records.
As an administrator for Alma, it would be helpful to have the ability to sort subfields in holdings records. For example, I was adding a subfield 3 to 583 holding records via normalization rules and the subfield was added at the end of the holdings tag. I desired the subfield 3 to be listed first in the 583, but it was not possible to do.
