Unfortunately the database is a third party product (a social care case management system). We can’t add our own functionality to the BO universe either - it’s locked down plus we don’t have the in-house expertise to do so (and to maintain any local changes).
Fortunately, it isn’t generally an issue for current or recent cases; it’s only when we’re looking at historic records for data quality purposes or with a view to archiving records. I’ll just have to make sure to create alternate ‘date’ fields…
