Certificate Store Name - Can you have more that one entry

It's sort of odd that the store name text box suggests multiple values, but the corresponding help text does not:

Specifies the certificate store name that the action attempts to match. The certificate store can be a system store with a predefined name like MY, or a user-defined name. The store name can contain alphanumeric characters. The Machine Cert Auth action treats MY as the default store name for both Mac and Windows clients.

For more information about MY, the default store name for personal certificates in Windows, see http://msdn.microsoft.com/en-us/library/aa347693.aspx.

For a Mac client, if you do not want to use the default location, you must type the name of a keychain file. Type only the file name, which is case-sensitive, without a file path. To view keychains, use the security list-keychains command from the Terminal.

My initial guess would be that 1) you should be able to put multiple values here, line delimited, and 2) you may not have to for a default Mac configuration. Here's another great resource that explains the "MY" certificate store:
