Thank you for the information that you have provided, @OCD,

The option to disable the Check image auto-import feature and remove multiple attachments at once is unavailable. I recognize the need for these features to help you manage your attachments. For the time being, I suggest you give our software engineers your feedback. 

To submit feedback, follow these steps:

1. Open your QuickBooks Online account.
2. Go to the Gear icon and select Feedback.
3. Type in your suggestion and click Next.
