Hany, thank you for your inquiry. Currently, an event is limited to one entry in From Address or From Domain. I can see the value of having the ability to add multiple entries in the From Address/From Domain. I have added it to our features request list for further consideration by the devs. I am changing this from a Question thread to and Idea thread.
A workaround is to create separate rules for each of the From Addresses or Form Domains.
