Restore a filegroup/file to a Point In Time (PIT)

Can i restore a single filegroup (or file) to a previous point in time (say 8am), but keep the rest of the database unchanged (say 10am).

Or, does the whole database have to be at the same point in time after a restore of a specific filegroup. Or is it that everything has to be the same PIT as the PRIMARY.

I'm not positive if you can restore a file to a specific point in time, but the database can do it, look: http://msdn2.microsoft.com/en-us/library/ms186858.aspx
