Direct Reports under different manager

As a company, we recently made an acquisition for a headcount of 83 in last month. All the members are tagged to TA manager for time being to get the onboarding and their email domains, system integration etc. So finally, as the Glint Survey is the snapshot of the time on that day they were tagged to the wrong manager and the very next day they were tagged to the right one. 

I raised a support request today. Can we retroactive update so that they go under rightful managers?.
