Thanks for joining this thread, RetiredLF.

It's a good thing that you're able to point this out. At this moment, QuickBooks Online Profit and Loss reports is designed to only have the all or nothing collapse option. In the meantime, you can make use of the suggestion 

I appreciate you for sharing your thoughts on how you'd like to customize this function. We are always open for suggestions that will help improve the product functions. Together with my colleague MichaelDL, allow me to pass through this suggestion to our developers for feature request.

For now, I encourage you to visit our QuickBooks Blog. From there, we share recent happenings and future developments and the latest news about QuickBooks and what our Product Care Team is working on.

You can always visit the Community page if you have questions in the future. I'd be glad to help.
