Thank you so much for informing us about this issue, @lmoCDS. I'll provide some information about this concern.

I understand the importance of having this report you've mentioned in the modern view of the report in QuickBooks Online (QBO). Since it's unavailable in the Modern view, you can still switch back to the Classic view of the report and pull up the custom report you created. Let's click the Switch to Classic view option on the upper right corner of the report to get you back to the old layout.

Also, you can send feedback to our product developers for this feature and other suggestions you have in mind. Any opinion is highly appreciated. 

We can click the Give Feedback option on the report base on the screenshot above or refer to the steps below.

Here's how:

1. Go to the Gear icon.
2. Choose Feedback.
3. Enter your comments or product suggestions.
4. Then click Next to submit feedback.
    

You may visit our QuickBooks Online Feature Requests website to track the status of your submitted feedback.

Please know that updating the features and layout in QBO is still ongoing. We appreciate your patience as they work on it.
