Dashboard: filter over multiple index patterns

Hi,

I have two index patterns, both containing a field "stage". Now in a simple dashboard I'm combining visualizations based on both index patterns. What I would like to achieve now is being able to define a filter for this common field "stage" so that all visualizations update accordingly. Unfortunately in Kibana 7.3.1 I'm forced to select a single index pattern. Adding two filters also didn't work because the second filter replaces the first one. Is there any solution I'm overlooking?

Even though you are choosing a single index pattern when creating the filter, it is applied to all visualizations no matter the underlying data source. Could you check whether there is already the right data showing up for all visualizations?

Ah, so I only have to choose a single index pattern in order to get the list of available fields filled? Guess I have misunderstood this.
