[Zope] Transient Object container/persistant add script?

[Michael Fischer v. Mollard]

Hi!
I ran into the following problem: I'm using the Zope session machinery 
and want to use add- and del-scripts with the *temp_folder 
<http://localhost:9673/temp_folder/manage_workspace>/session_data 
<http://localhost:9673/temp_folder/session_data/manage_workspace> ** 
Transient Object Container*.
I added them and it works very fine, but after restarting Zope the 
add/del scripts are gone. How can I make them survive a reboot?
