Can you add a custom domain for predictive text when writing an email address?

[1bellb]

I have my own domain and own all email addresses associated with it.

When I am writing one of my email addresses into a form and I get to the ampersand @ symbol, the preditive text gives me suggestions for gmail.com, yahoo.com and outlook.com. But is there any way of getting my own domain to show in those suggestions?

I tried using 'Text shortcuts' when I type the ampersand @ symbol, but that only works if I type ampersand on its own. Any other ideas?

U can use text shortcuts if u perfer something like JJ replace it to email of choice

The email can be anything.

random@mydomain.com

something@mydomain.com

another@mydomain.com

etc....

So when I type "anything@", I want it to suggest adding "@mydomain.com" to give me "anything@mydomain.com" without having to type it all out all the time.
