Hi @Donnie Harman,
Thank you for posting in this community.
Unfortunately, we can't add a thumbs up option on SharePoint Lists at this time.
But we can rate and like items in a SharePoint List.
You can try to see if these two options meet your needs. Here are the steps to set it up:
- Go to List or Library settings.
- Click on Rating Setting.
- Enable Ratings by clicking Yes radio button and then choosing either Likes or Star Ratings.
Reference: Add a ratings feature to your library.
