Change Default sorting order of content

Summary:

We are looking for way to change the default sorting order of content in communities to Title A to Z. We have tried looking for common lookups and even tried page composer, but we cannot find a way to change the default sorting order from Highest Rated to Title A to Z.

It appears that the system is taking the first value in the list, so we were hoping to just re-order the list, but there is also no way in the system to do so:

Anyone got a similar requirement and was able to change it?
