Feature - Default Index filter order

While keeping in mind possible performance issues, there are a few cases where I want more than one index on the main page of a tab, so I’ve turned on the Default Index setting to show the filters I want.

I want one filter first and other filters to follow, but I cannot find a way to affect the order of the filters. How is the order of Default Index filters determined? Is there something I’m missing that will allow me to affect the order of Default Index filters?

Order the filter of filters as they are loaded so you choose what comes first, second, etc
