No and no. But you can export the Pages to PDF, and then open the PDF in the "BETA InDesign 19.4" in order to convert to a new ID file. This might not work wonderfully well. Word docs can link to ID but it is a one-way street going in. Also, you would have to take care to use paragraph and character style names in Word and ID that are identically-named. Further still, the Word paragraph styles should be independent styles; not styles based on Normal. Nor should ID styles ever be based on Basic Paragraph Styles. If you need 2-way text editing, you would adopt the use of InCopy for the linked text (instead of Word).
Another brand-new feature is the fact that ID docs can be stored in the Adobe cloud and other editors could open and edit the text in the layout. I have not used this new feature yet!
