Add in a sorting or filter feature to quickly find Custom Exercises that:

• Have no video, have a custom video, or have a linked YouTube video
• Don't have description text

Often I will quickly add exercises from YouTube if it is something that I need for a client's plan but haven't filmed yet (and isn't available in the Trainerize Library). I then go back and fill in these exercises with my own custom videos when I have the time, and it would be nice to be able to sort and find these quickly.

The same applies with Exercise descriptions. Sometimes I will upload Custom Videos to make them available, and then go back in the future to add exercise descriptions and cues. Being able to filter "blank" descriptions would be incredibly helpful for finding which ones I still need to update.
