Yes, you can achieve that with this tweak:
- Install and publish JA OSM
- Edit the layout file of article:
ROOT/templates/ja_trip/html/com_content/article/tour.php or
ROOT/templates/ja_trip/html/com_content/article/tour-2.php
- Look for this snippet:
{jamap locations='{"location":{"0":"<?php echo $location ;?>"},"latitude":{"0":"<?php echo $mapLat ;?>"},"longitude":{"0":"<?php echo $mapLon ;?>"},"info":{"0":"<?php echo $mapInfo ;?>"}}' }{/jamap}
change it to:
{jaosmap locations='{"location":{"0":"<?php echo $location ;?>"},"latitude":{"0":"<?php echo $mapLat ;?>"},"longitude":{"0":"<?php echo $mapLon ;?>"},"info":{"0":"<?php echo $mapInfo ;?>"}}' }{/jaosmap}
