Clear all checkmarks

I use a combination of the checkbox and indented bulleted text within some of my tasks for app testing to help identify the testing parameters that need to be met for completion (see attached for an example). I reuse the task for testing purposes, so after I am done and I need to test again, I need to clear the checkmarks. Can there be an easier way to clear all the checkmarks at once while keeping the checkbox as is?

Currently, I have to go and highlight the text, select the checkbox, and then reselect it. While that would not normally be an issue if all my text was a checkbox, when I have bulleted text in combination to the checkbox, I have to highlight partial blocks to not include bulleted text or individually unselect each checkmark.

Thanks in advance!
