Virtual Fax Ooma office Log in

I have Ooma Office with following-
Ext 100 Virtual Receptionist
Ext 101 (1st identity) with phone ###-###-##15
Ext 102 Virtual Fax (2nd identity) with different phone number ###-###-##24

Should I not have the ability to login to Ooma Office Manager under/as extension 102 to send fax?
At this point I only have ability to log in with 1st identity phone ###-###-##15 then change outgoing fax number to ##24.
Fax will send BUT displays identity of Ext 101.

I originally went route of using linx with actual fax on ###-###-##24 but fax reliability was poor at best.
Contacted Ooma via chat…they referred me to voice number to address my concern.
Contacted Ooma verbal support last week and today to resolve problem concern. Both times after approx 5 minutes of courteous customer service the line was disconnected without resolution.
