Support for variables in Stored Subset when used in a Dynatable

In a canvas report, I would like to use the month dimension as a hierarchy filter for the columns in a Dynatable.
Example: In the combobox of the canvas report in dimension Month I select 2026. In the columns of the Dynatable it should show all months of 2026: 2026-01, 2026-02, etc. If the user changes the combobox to 2027, then the columns should automatically change.
Same should apply to rows. If I choose in a combobox a Product hierarchy like Product categories, then it should show in the rows all products regarding this selected product category.
