Importing API replaces modified collection


we started to use the feature for API import of collections. During testing we often adapt the request bodies to suite our manual tests. When a new version comes, importing the new YAML kind of overwrites everything we adapted in the requests so far and we start at the beginning.
When doing the update I get a list of changes that are going to be restored to the new YAML definition but I can’t deselect any of them.
Since we mostly use POST requests, the bodies have to be altered to get a valid response, since the bodies in the YAML are just an example and won’t work with real data.

Is there a way to avoid that?

Thanks for your help,
all the best
