I have an open ticket with Support regarding this, but wanted to throw it out here to see if anyone else already found a solution to it.
The situation is that I have a Series Map that has a tab that is a Tour Map. I was wondering if there is a URL parameter that will allow me to open a specific point in the Tour Map in the Series map. So the Series Map comes up, opens the tab with the Tour Map, and Tour Map goes to a specific point.
I was thinking it would be something along the lines of http://encinitas.maps.arcgis.com/apps/MapSeries/index.html?appid=abcb1e41a88e41f7b87aab875d988179&entry=2&index=3 , but it is only taking me to the tab with the Tour Map.
Hopefully someone else has figured this out!
