Custom-app override the customer-quick-entry

In the quick entry form for customer and supplier, the mobile number field has the field type “Data” set in it, but I need to set the “Phone” type in it. Is this possible?
If yes, then how can I do it?
Please help.
Thank You.

Can anyone guide in this please.
