Sending pages file as word document without export

I used to be able to share a pages file to my PC colleagues directly in mail by sharing the document as a word file, this meant that I did not need to create a separate word docx file and then send it, now it appears I have to first export the pages doc to a word file, and then send that meaning that I now have two copies of the file. can you bring back the old system please which was intuitive and less clunky

thanks
