What we've done in the past is to do this in the arguments sub. (Which,
yes, is deprecated, but I haven't yet spent enough time with the param
syntax to know the answer with it off the top of my head)

sub arguments {
    my $self = shift;
    return $self->{__cached_arguments} if (exists $self->{__cached_arguments});

    my $args = $self->__get_cache->{$self->__cache_key($self->record)} ||=
        $self->SUPER::arguments();

    if (my $owner_id = $record->owner->id) {
        $args->{'owner_id'}{'default_value'} = $record->owner->email;

        if (   $owner_id == BTDT::CurrentUser->nobody->id
            or $owner_id == $self->current_user->id )
        {
            $args->{'group_id'}{'valid_values'} = [
                {   display => (($record->group_id ? $record->group->name : "Personal" ) . " (Unchanged)"),
                    value   => $record->group_id,
                },
                {   display => 'Personal',
                    value   => 0,
                },
                {   display_from => 'name',
                    value_from   => 'id',
                    collection   => Jifty->web->current_user->user_object->groups,
                },
            ];
        }
    }

    ...
   return $args;
}
