Help: how can I add custom alert for unique field

1

Hello all
I have assigned Email to be a unique field for volunteers

So when a volunteer is added with duplicate email, it displays an alert
Email must be unique
See on screenshot below

My question is that is there a way I can create custom alert for unique field?
For example instead of saying Email must be unique, it can say something like Email already registered?
Thank you all in Advance
Current instance
ERPNext: v10.1.80
Frappe Framework: v10.1.70
