Adding a domain for RLS

Hi All,

I wanted to know if there's a way to add a common email domain name for row level security.

For example:- 

There are 100 people with email @mycompany.com , I want to provide all 100 people with "@mycompany.com" email address the access and NOT add each person one by one under Dataset-->Security.

Can I add everyone with a common email domain? Is it possible? If yes, how?
