Hello @nickmannion ,
From my understanding of the Adobe Experience Platform (AEP) documentation, you can currently add only one split. This allows you to create a single split and generate multiple audience outputs, either by percentage or by splitting based on attributes.

However, I’m not sure what your specific use case is or why you need multiple splits.
If you’re thinking about a scenario where you have Audience A, and you divide it into two parts (e.g., Audience B with 50% of Audience A or based on specific attribute conditions, and Audience C with the remaining 50% or other attribute conditions), and then you want to further split Audience B (e.g., into Audience D), you would need a slightly different approach.
Instead of performing multiple splits, you can combine the logic of Audience B and Audience D into a single segment. For example, if Audience B consists of people living in the US, and you want Audience D to consist of men from Audience B, you can combine the conditions (i.e., people living in the US and being male) in one step to get the desired output.
I hope this helps clarify things!
Best regards,
Parvesh
