Drill-down and how to reset to the highest level?

Question

Good Morning,
A second question on drill-down:
My dashboard page still looks like this:
Dummy Prompt 1: YearFrom
Dummy Prompt 2: YearTo
Prompt 3: Item
All three prompts have a presentation variable to show their respective value in the title of the dashboard page.
Below the prompts is the report, which is filtered by the three prompts and contains a column "year" with the option to drill-down.
When I drill-down on a "year" value, a column "month" appears and shows the values of the year by month.
Problem: In order to start a new query, the first query values have to be reset (I implemented a button for this) to get back to the "year" report. This is not obvious to the user.
Question: Is there a way to implement the "Reset" button into the "Go" button or another way to avoid the reset for the user?
Again every idea is appreciated

The reset button does not work because when anything is entered in the operator field, and you press "reset", two events occur (1) a change is detected in the operator field and (2), a change in the reset is detected. Event (1) occurs first stopping the loop. The reset case is thus never reached.
One solution would be to sense the reset state in the "operator" event. You need to keep the loop running if reset is pressed. (See attached modification.)
Some other suggestions: Notice that I also made a data dependency between the case structure and the while loop. Without this, there is no guarantee that the case structure executes before the while loop and you might generate a race condition with unexpected results. I also re
moved the timeout event, it doesn't seem to do anything. The three text fields should be set to "limit to single line" in this application so fields can be finished by hitting the enter key).
