Hi,
It is possible but probably not a good idea: only queries from the same called AE would work, since conquest would compare the called AE with the one in the database for every query. I believe someone tried this before. What does work is to add another (unused) tag to the database, and have an ImportConverter copy the called ae to this tag (e.g., ImportConverter0 = set 9999,9999 to "%c")
