Is is possible to have multiple RBS BLOB stores used by a single content database?

I am working on backup/restore software for SharePoint 2010/13 and need to know if it is possible for a user to configure multiple BLOB stores for a single content database.

i.e. In the steps to create RBS BLOB store when you run:

...

ALTER DATABASE [ContentDbName]

ADD FILEGROUP RBSFILESTREAMPROVIDER CONTAINS FILESTREAM

and

ADD FILE (name = RBSFilestreamFile, filename = 'c:\Blobstore')

    TO FILEGROUP RBSFilestreamProvider

Is it possible for there to me multiple FILEGROUPS or multiple FILEs per FILEGROUP?
