Read the DD post and ask the two drop-down boxes to jointly query how to do this.
I tested the experiment and posted the results for you to learn and analyze ..
1. First, the query interface is displayed. The current interface displays three fields: Month, Indicator Name, and indicator value.
2. On the Value prompt page, create a value prompt. Now, create two values: Month and Indicator Name, which correspond to parameter 1 and parameter 2 respectively.
3. now is the key step of configuration. In the first value prompt, there is an attribute column in the lower left. One column is called regular. In general, a subitem is called automatic submission. Select Yes, the stack source is empty. In the second value prompt, select "no" for Subitem automatic submission, and select parameter 1 for Stack source selection.

This is the result.
