Question on "Saved Issue Type Lists..."

Hi all,

when creating a query in Scarab you may use pre-defined issue type lists.
Such a list will automatically hold a reference to the user that created
it (the currently logged-in user). As a consequence the lists are
maintained on a per-user basis (Jack will not see Jims lists and vice
versa). Is there any possibility to create such a list for all users?

I'm asking because when I had a look into the underlying database tables I
found some entries in the SCARAB_MIT_LIST with a <NULL> entry in the
USER_ID field. I wonder how these entries got there?
And furthermore I was thinking about updating an appropriate list
definition to a <NULL> user directly on the database to make it publicly
available. What do you think?

Probably we would need some maintenance screen that deals with pre-defined
issue type lists?

We are using a b20 release here, and a b21 is out of reach at the moment.

Regards
Torsten
