Feature to Structure

Is there a way to convert a feature into structure and structure into feature easily? and if no it should be added, this is cuz when im downgrading my mod, 1.16.5 doesnt support structures so if i wanna have the structures in older versions, well yeah you get it. also a while back where an mcreator update made structures into features, i sitll havent finished converting my features back to structures cuz im lazy so yeah. if there is a way for this please someone tell! and if not, add it to mcreator or make a plugin for it, thanks!
