Whitelisting domains in Barracuda

Greetings all -

I'm looking for a shortcut to the following process, instead of going into each domain and whitelisting a single domain.

I need to "add"/"Whitelist" a single domain for about 90 domains we host email for.

Would rather not have to go into each individual domain, just to add a single whitelisted domain.

Hope that makes sense.

TIA

MK
