I'm working with two canvas pages, canvas1 and canvas2, both equipped with identical filters. My objective is to have the filter on canvas2 initially set to the first value by default, while the filter on canvas1 should default to displaying all values. If a selection is made in the canvas1 filter, it should automatically update the filter on canvas2 accordingly. Additionally, if 'All' is selected in the canvas1 filter, the filter on canvas2 should revert to displaying the first available value.

I've attempted to address this by creating a parameter for the canvas1 filter and enabling the 'First in List' default value option for the canvas2 filter, using the parameter from canvas1. Initially, the canvas1 filter correctly displays the first available value. Changes made to the canvas1 filter are accurately reflected in canvas2. However, when I select 'All' in the canvas1 filter, the canvas2 filter also defaults to 'All', whereas I expected it to show the first available value

Any suggestions you have would be helpful. Thanks in advance!
