Yes, I know of that syntax.
I was more interested in how to affect all articles in the publication without specifying them explicitly.
The "WHERE" clause is the same everywhere, so, I hoped, it would be possible to update all the articles at once.
As a workaround, I was hoping I could get a "CREATE PUBLICATION" command syntax from the DB without unloading the whole DB. Then, I could do a quick replace of the where in the file and then run the "ALTER PUBLICATION" command with the new syntax.
