We always want to hear from our customers on how you want our product to be developed or in terms of adding new features. Please know that I am sending your idea to our software engineers. Let's see if this idea will be given a chance to be added in the next product updates.
If you have more something to share with me or need assistance with QuickBooks, just leave a comment below. I'll respond to you as soon as possible. Take care!
