Thanks for following up with the Community, david407. I appreciate your detailed information and screenshot.

I can certainly understand how an ability to add new products with a slash (/) character in their names could be useful and have submitted a suggestion about it as of today.

You can also submit your own feature requests while signed in.

Here's how:

1. Use the Gear icon, then go to Feedback.
2. Enter your suggestion(s) in the Have feedback? window.
3. If necessary, attach a file with your Camera icon.
4. Select Next.
   
   

Your feedback's definitely valuable to Intuit. It will be reviewed by our Product Development team and considered in future updates. You can stay up-to-date with the latest news about your product by reviewing Intuit's Product Updates webpage.

I've also included a detailed resource about working with products/services which may come in handy moving forward: Add product & service items

I'll be here to help if there's any additional questions. Have a lovely Tuesday!
