I understand want you want but it's just not the right way
and will probably not work. Adding links during ticket creation
is not documented, but it's not hard. Just pass an option
with the link type and the id of the ticket you are linking
to. For example:

   $ticket->Create(
        Queue => 5,
      Subject => 'test',
       Parent => 234,
    DependsOn => [ 189, 190 ]
              .
              .
              .


As you see you can link to multiple ticket by passing
and array ref instead of a single ticket id.
