Hello LI_Dave:
You can add the processor from Components Library -> Processors:

The wizard will prompt you to select the package.
:smileyalert: The wizard will also ask you about the compiler. Make sure that GNU C Compiler is selected, since it is the one used by KDS.

:smileyinfo: The drawback is that you need to replicate the CPU settings in this new component.
You can choose to remove the previous CPU or leave it so you can jump back to that one if you wish using the context menu -> Component Enabled:

Regards!,
Jorge Gonzalez
