Adding mailboxes to an InPlaceHold eDiscovery

Question

Using PowerShell, is there a way to add, or append, source mailboxes to an existing mailbox search? I unfortunately found out the hard way that doing
Set-MailboxSearch -identity "December2013" -SourceMailboxes [email protected]
will in fact REMOVE all the source mailboxes that were already there, and REPLACE them all with this 1 source mailbox--not a very good idea.  So is there some kind of undocumented "-appendsourcemailbox" or "-sourcemailbox ++ user1"
sort of parameter that can be used?
I know that if I use the EAC, I can add more, but the in palce holds that I do tend to have dozens of users at a time and I'd like to keep them grouped by holds named "MonthYear" like in the PS code above.

Hello,
The "-appendsourcemailbox" parameter doesn't exsit in Set-MailboxSearch cmdlet.
