Customize detail view links (click to WhatsApp)

Customize detail view links (click to WhatsApp)

Is it possible to customize the detail view to include links in certain fields? For example having the phone number link to start a WhatsApp (wa.me/phonenumber) chat instead of dialing. Or linking a field like invoice number to take me to a different report on my app.

I know it's possible to make custom record templates but these are used for printing and saving to PDF. I am looking for a way to customize the actual detail view while viewing a report.
