Target API audienceRule exclusions

[c1dh]

My team uses the Target API for the creation of offers, audiences, and activities, transitioning away from the UI. 

When building audiences in the UI it is possible to set exclusions for groups of audiences. Is there a similar functionality to do this when creating audiences with the API? Or is our only option to copy the individual audiences and set up the exclusion at that level with targetRule?

Something like the example below where audience4 or audience5 would be excluded from audience3.

ex.

• "audienceRule": 
  • "and": 
    • audience1,
    • audience2,
    • audience3
      • "excluding": 
        • "or": 
          • audience4,
          • audience5
