Save session state / modify analysis file from webplayer

I've created python script to attach / remove tags in Spotfire, the script is similar to the one in this post and it works well both in desktop app and in webplayer.

My issue is with webplayer, whenever I close the analysis and reopen it again my changes are lost, tags are restored from the original analysis.

I've tried saving the link of the session and reopening again, however I keep getting error:

The task could not be compoleted.

File '...' not found or access is denied.

Also I've tried looking for information on session, but couldn't find anything useful.

Is there a way to save changes made in a session? (either saving state per session or modifying the visualization would be a solution for me)
