Suggestion enhancement: customize password field name

DISREGARD!

I have just realized i CAN change the name, from "Text" to "Domain".

Sorry !!!

Thanks.   I am not sure this is what i actually need.

I need to add a field to an entry.  The field is not a "Text, URL, Email, Address, etc..."  it is something else.  I am trying to add a new field that will be called "Domain", but i cannot find a way to change the field name or customize it. 
The entry already has a username, a license key, a password, a URL, etc.   I need to add a field to this entry.  I did not want to create a new entry with a "Title" = Domain.

any suggestions?  

TIA !!
