Lots of good advice here.
Age a few days less in the walk in and get into processing bags. It's happened to me, too, and +1 on the dog. On my elk this year, I took EVERYTHING and gave lots of trim to my pup. She can eat for weeks!
If your goal is to get good aging on big muscle cuts, keep in mind that you can continue to age AFTER freezing and storing. Simply ask your butcher to put major muscle cuts into a large chamber sealed bag. Good butchers should be set up to do this.
Then, you can bring out a large bottom round (for example), and let it thaw and continue to age in your fridge. My family will cut steaks off a big leg cut like this for a week plus. The meat ages (very slowly) in the freezer too.
In short, it's helpful to consider that aging does not have to happen all at once. You can piece out the muscle breakdown process over time.
