Use a different 'Calculated on Measure' for Limitations

[QlikkitySplits]

Hello,

I need to use a different measure here under limitations tab. i want to have the top 5 lines by default, and use a different measure (num_success).

This line chart has two dimensions:
- Procedure (Line)
- MonthDate (Group)

and one measure: 
- Success Rate

Lines is a variable.

How do i change which measure this uses to limit the data set to the top 5 procedures with the highest num_success (not success_rate)?
