Include a smart collection into a standard (fixed) collection ?

Hi Community,

the title says it all. Is there a way to make a smart collection part of a fixed collection? Drag and drop does not seem work.

Background: usually I create a basic smart collection about an event. The selection criteria is based on a specific keyword. And every now and then I need to extend this basic collection with some more selected shots for other customers.

Adding this specific keyword is no solution - afterwards I will have to remember the added shots and have to remove the keyword.

Adding another temporary keyword is no solution as well - keyword handling in Bridge is as challening as brain surgery.... it's just too easy to mess them all up. So I strictly want to avoid unnecessary operational keywords.

My idea was to just temporarily create a fixed collection, add the smart basic collection, and add some more selected shots for my purpose. When I don't need the fixed collection any more I just delete it. No keyword messing up, the basic smart collection remains untouched.

Thanks for your comments and ideas!!
