Most dashboards include at least one metric within an indicator widget. It would be incredibly useful to be able to use this value as a variable for use in other indicators. In my use case I have a Covid-19 Dashboard which displays 4 indicators. Total confirmed cases, total recovered cases, total deaths, current number of infections. In order to display these values, I had to use a number of methods including filters and also writing a value as text. If I could have simply referenced the first two indicator values, I could have subtracted the total recovered cases from the total confirmed cases (minus deaths) to get the number of current infections.
