For now, you'll only have the option to manually click your default email subject line instead of using the suggestion from Intuit Assist, pmoriarty. It would also be great to have the option to turn off the feature.

I suggest sending a feedback request to our product developers. They will review it and may consider adding this functionality in future updates.

Here's how:

1. Go to the Gear icon.
2. Then select Customer form styles. Locate the Standard template.
3. Select Edit. On the Content section, mark check the Description field.
4. Once done, click Done

If you have other QuickBooks-related concerns, don't hesitate to reply to this thread. I'll be looking out for your reply.
