I am not aware that you can do this.  My understanding is as follows:

A single node N can be a member of two partitions, say A and B, but as
soon as a job starts on N in partition A, then while the job is running,
any remaining resources on the node are only available via partition A.
A second job can only start on N in partition B if no jobs on N are running
in partition A.
