Hi Eric-Motion,
Thank you for your time!
I've confirmed on my Mac machine that there's the "Pick a Category" option via To-do web client, while there's none in the To-do desktop client on Mac. I've further tested and confirmed that you may access this feature by using Tasks in the Outlook for Mac desktop client.
 > Microsoft To Do. This Feedback portal is a new Microsoft service that allows customers to see all the feedback they've given Microsoft, the status of that feedback, and any official responses from Microsoft about the feedback. Thank you for your understanding!
Hope it helps! If any update, welcome to post back.
Thanks & Stay safe,
