Is it possible to insert a field at specific offset instead of appending to the tail?

Description

Hello folks.
I got mod for a game with serialized class and fields. The fields must stay in order with serialized data.
Then the game updated, inserted a few new fields in the middle.
Then I tried to add the new fields.
But they are always appended to the tail - wrong order.

So what should I do?
Does dnSpy support rearranging order of fields?
Enlighten me please. Thank you!
