Hello Oksana Karasyova, thank you for your patience; we have introduced this feature in our recent release.

Previously, in view history, you could only delete one article/page version at a time. You can now select multiple versions of the article/page that have been forked from and delete them all at once. This action would be recorded in your Team audit, and an notification would be sent to the admin/owner as well.

Thanks for your feedback, We added this feature in our pipeline, Once we started implementation, we will update you.
