Can I force a new referral if a referral exists already?

I have manually uploaded a referral but there is already an old one in the system.

Yes, you can force a new manual referral if there is already one in the syste,

When you click the + icon to manually upload a new referral, you will have the option to "Force a New Referral”. This will allow you to create a new referral, even if one already exists for this patient.
