Adding Provider Direct Addresses

Each time I need providers adding to the Direct Addresses in eCW, I have to open a ticket and provide each direct email address in order to see the provider in the Direct Trust list for referrals. Shouldn’t there be a way to provide the end of the address and have all addresses for that organization loaded? For example, an organization gave me a list of 2,000 addresses all with the address of @direct.osfhealthcare.org. One would think this could be imported as a community? Or is this wishful thinking on my part.
