transfer 485 from one 140 to a

I submitted my first I140 alone my second 140 concurrently with 485/765/131 (and those for my wife).

Now my question is:
if my first 140 was approved early, how can I transfer my 485 from the second case to my case?

If you know the answers or have similar experience, could you please email me at: [e-mail]

billions of thanks!
