Hey! I figured this out! I wouldn’t call my work around simple exactly, but it works! I too was surprised that HubSpot didn’t have this report natively. I built a workaround using HubSpot workflow and webhook, Zapier and Google Sheets. I’ve implemented it for a few clients in our agency and it’s working great so I created a tutorial on how to set it up. I was measuring from SQL lifecycle stage entered but you should be able to tweak it to measure from MQL. Also would be happy to help anybody trouble shoot while setting this up so we can get it working for you.
Here is the link to the tutorial: Instrumental's Blog
