MARK ALL OPTION
When you mark a transaction personal, you'll see it change and give you the option to MARK ALL.
If I check this, you'll see that other transactions with the same name, are also marked as personal, saving you having to click through the same transactions again and again.
TAXOD also remembers to mark it as personal on any future transactions with the same name. You just need to hit confirm.
You can deselect just one transaction by marking it as Business on the web app and swiping right on mobile.
You can just as easily unmark all by hovering over one of the records and checking UNMARK ALL.
