On startup I would like to set a session custom property. I cannot figure out the full tag path  
I have tried session.custom.mytag.  
see some stuff about using system.perspective.getSessionInfo[id]  
we are running 8.1.0 but doesn’t seem to support above system.perspective

Consider using an expression binding with just the constant you wish to start with.

I am leaning the various functions within Ignition and was hoping to use a session custom tag.  
I have a project with several views that I would like to use an endDate that is now when the user starts the project, but as they drill down on the date, I would like this date to be able to pass from one view to another, so that’s why I wanting to use a session custom tag.  
Thanks for any suggestions and guidance

My recommendation was for use with the session custom tag. Create the tag. Add the expression binding to `now(0)`. The “0” will keep it from executing again.

That worked. Thanks. Only issue I had was that I did not click bidirectional on my date picker so was not updating the session custom property.  
Thanks again for the help
