Performance Admin page (RUI): make Performance Document filter required

Summary

How can we make the Performance Document filter a required search field on the Performance Documents Responsive UI search page?

Content

We are looking for a way to make Performance Document to be a required field to search for Performance Documents (just like the Review Period field is required). For example, is there a way to do this in Design Studio, page composer, etc?

The reason we want to do this is because the Current Task filter dropdown is blank without selecting something in the Performance Document filter. So we believe the user should be forced to select a Performance Document, so that they can see values in the Current Task filter. With the way the page is designed, it’s necessary to select something in the Current Task filter in order to move the task backwards or forwards.
