Multiple export to an unique page

Is there a way to export multiple time to unique page ?

From WMS Leaflet map GCA / Patrick Brockmann / Observable, I would like to export
different maps and have them synchronized (Leaflet has a plugin for that GitHub - jieter/Leaflet.Sync: Synchronized view of two maps.).

Is someone has coded such Observable notebook ?

Have implemented this from example.

How to do this from an export ?

The cells that are exported in the embed view are listed in the embedding url. If you give a name to the cell, it should be possible to export it?
