How to merge 2 Apple Watch’s data into one

I recently received an iPhone 12. After transferring all of the data from my XR to my 12, my Apple Watch did not automatically sync. After troubleshooting with customer service I had to reset my Apple Watch. Now all of my past activities and earned awards are not there. I looked into settings, health and found that there were 3 different Apple Watch devices listed-weird?! One of them containing past data with multiple workouts and earned activities and another with activities from today moving forward. How can I merge those devices together so I can get back all of my earned awards and progress?

I have searched this forum already And I found the same type of question from 2017. This was a known issue then but I’m wondering if Apple has developed a solution to this since then?
