Can I add two or more position markers on the fly in OSM…?

Hi !

I'm using a feature of OSM that allows to create "on the fly" in the URL of the map a single marker. (See below)

https://www.openstreetmap.org/?mlat=-31.611464&mlon=-59.303043

Now, I want to add simultaneously two or more markers in different locations using the same technique.

Anybody knows if this is possible?

Thanks in advance
