Is it possible to open a .mscz file from MuseScore 3 in MuseScore 4 without losing the manual note offsets?

Is there a way to open a .mscz file from MuseScore 3 in MuseScore 4 while preserving the manual note offsets made using the "Piano Roll - Position"? I have a large score with many manual offsets to achieve the desired note timings, but when I opened it in MuseScore 4, the offsets disappeared, causing the score to sound incorrect.
