Using database to fill in properties on a given datagroup item

Hi,

Is it possible to use an access database to puplate the information in an architectural or structural datagroup item? Like we have with pipes for example, where we choose the database and select from a list of items that exist in that database...

Funny thing, I've tried the "add instance data" tool with a straight pipe, on a simple microstation solid, and using this tool I don't get access to the database... nor if I try to modify it's instance data after-the-fact.
