Let managesieve-vacation plugin insert default tests in every users sieve script, without the users see them on UI? Or do I need to modify the code for this?

default tests to insert: if allof (not exists ["list-help","list-unsubscribe","list-subscribe","list-owner","list-post","l ist-archive","list-id","Mailing-List"], not header :is "Precedence" ["list","bulk","junk"], not header :matches "To" "Multiple recipients of*")

so I need to have something like this:

require ["vacation"]; # rule:[Vacanze] if allof (not exists ["list-help","list-unsubscribe","list-subscribe","list-owner","list-post","l ist-archive","list-id","Mailing-List"], not header :is "Precedence" ["list","bulk","junk"], not header :matches "To" "Multiple recipients of*") { vacation :days 7 :addresses ["roundcube-test@unifi.it","rc-test@unifi.it"] :subject "assenza" text: -- risposta automatica --
