Add the ability to group titles together for faster filtering of lists. For example, I am often filtering lists to pull "CEO", "CFO", "CTO", "Controller", etc. If I could group them and give it a title like "C-Suite" that would be super helpful. That way when I go to the list filter I can just click "C-Suite" and it will pull the titles I assigned to the group. My current workaround is cloning lists that have the filters I want and then changing all of the other filters.
