This would really help if it can be set at the Payee level. I'm not looking for a universal option that turns off all autofill.
This is a bad bookkeeping practice, and this feature continually introduces errors, which also affects the budget. It would be better to default to no autofill. When you go to Target, do you always buy the same thing for the same price? So you only buy clothing, or you only buy groceries? The same thing every time? Or, do you buy things that would span several categories, and different categories on each trip? This does it on automatic downloads, as well as manual entries. I've voted. :-)
The lack of an option to turn off auto-categorization is the reason that I am considering leaving Quicken after 20 years myself.
