I am only able to view the filters that are part of my default index pattern on my dashboard

Hello,

I have a dashboard, and using controls visualization on the dashboard. I am able to view and select the fields in my controls drop down, but when I apply the sections, those fields are not getting recognized by the global filter. Upon debugging further noticed that "Add Filter" link in the global filter is only allowing the fields that are part of my Default Index Pattern. When I change my default index to the index pattern used in my Controls visualization, then everything is working as expected. Is that a limitation or there is a hack to deal with the situation. My tenant is having so many index patterns, and this is becoming challenging when there are multiple dashboards using different index patterns.

Appreciate your help in this regard.
