Yes, I thought about something like that. Thank you.

The first solution seems much better for me because there is one filter
defined and used for numerous sources. One list defined and stored in
one place. In the second case I have to modify each driver configuration
separately. Information redundancy and distributed filters in rapidly
changing environment ("migration in progress") may lead to
inconsistencies which is undesirable...
