I'm sharing insights about undoing reconciliation without using QuickBooks Online accountant, Breeeze.

As mentioned by my colleague above, you can undo the entire period at once using QuickBooks Online Accountant.  At the moment, the ability to permit the admin level is unavailable in QBO. I can see how the functionality would be beneficial to your business.

 I'd recommend sending a feature request directly to our Product Development team. This helps us improve your experience and the features of the program. 

Here's how:

1. Go to the Gear menu and then select Feedback.
2. Type in your feature request in the description box.
3. Once done, click on Next.

I'll add these helpful articles for future reference:
