In Pilot2ATC 04.0 User Guide for version 2 , the guide to use at the moment , a web URL that is pointing to 

usable charts can be saved as following the description.

And making it available the next time .

In the new version 3 , URL's  can not be saved , but I can be wrong ...

You are correct.  That feature is not yet available in V3.

We are still working on functionality for the Charts panel.
