Feature - filter by related module count

On e326.0 you can not search something like “Give me all assets risks that have at least one risk associated with them”. We miss a “Count” of sorts when the field search returns a list of things rather than a string.

The only way to do this is by creating a status that triggers that condition and then filter against that status.
