We have requesters that are internal (our own staff) and also external (our customers). I would like to create requester groups for both requester types, but based on a condition otherwise we will have to manually organise the groups.

My thinking is that it would be good if I could create a new requester group (Internal), and set a condition based on the requester email address containing a specific value (our email suffix).

For example.... Add members to group where "Requester Email Address" contains "@ourcompanyname.com".

And then for the External group I would do the same but set the condition to, Add members to group where "Requester Email Address"  does not contain "@ourcompanyname.com".
