bbv2-m10: how to differ .obj build dir by using <define> (similar to debug vs release)?

Hi,

When building release vs debug, the .obj directories are automatically 
different so I don't have to do a clean build when switching between 
them. This works great so I'm wondering if a similar feature exists to 
work with a specific <define>.

Basically, I'm trying to avoid having to do a clean build when switching 
between 'standard' and 'professional' builds of the project which is 
controlled by a <define>.

I'd like these preprocessor-controlled 'standard' and 'professional' 
builds to use a separate dir for .obj files during the build.

Any suggestions or workarounds would be deeply appreciated.
