Are we able to avoid reassign field-id when building TableMetadata?

[mapleFU]

TableMetadataBuilder::new will always reassign_id for input. However, here I have some existing data files and may want to respect existing ids. But reassign_ids would not respect these ids. How could I build these id without reassign ( But I may need some checks to ensure the passed input is right) ?
