AM2632-Q1: Problem with Syscfg in Code Composer not allowing configuration of multiple channels for a SPI port

Tool/software:

We have a project in code composer for the AM2632-Q1.  Attached to a SPI0 are two devices that require different clock phase.  The best solution would be to configure the SPI port as multi-channel controller.  I have tried that.  However, Syscfg does not offer the ability to add an additional channel.

I tested this in one of the sample applications in the SDK.  It works as expected.  

Sysconfig is not providing a reason why this cannot be done.  Are there issue that would block this ability to add multiple channels.  For reference we are using the SPI controller in 3 pin mode.  We are managing the CS signals to the attached devices.
