You will need to speak with the Dovecot developers, to see if the
functionality is supported.

Note that the Sieve language does not mandate any specific behaviour:

"The "fileinto" action delivers the message into the specified
mailbox. Implementations SHOULD support fileinto, but in some
environments this may be impossible. Implementations MAY place
restrictions on mailbox names; use of an invalid mailbox name MAY be
treated as an error or result in delivery to an implementation-
defined mailbox. If the specified mailbox doesn't exist, the
implementation MAY treat it as an error, create the mailbox, or
deliver the message to an implementation-defined mailbox." , par. 4.1

This functionality is not a part of the base Sieve language or any
"official" extension, AFAIK.
