Easier to use Split-Apply-Combine

[brandon]

The community could benefit from easier integration of splitting and applying functions to grouped data. The summarize tool is great for splitting your data and applying summary statistical functions. It would be super useful to take that block just one step further, and allow users to apply any other (aggregate) function to their grouped data instead of just the built-in functions in the summarize tool. I would envision that aggregate function either being a custom function that is a combination of existing user-specified functions within Alteryx (e.g. in the formula tool) and/or even an interface that allows you to use other Alteryx macros on the grouped data.

Apply user-defined functions, or other powerful Alteryx macros to grouped and data is a very common operation in the data analyst's daily workflows and being able to apply them without reverting to batch/iterative macros in a seamless manner would be naturally helpful.
