NSSharingService - Remove facebook and twitter and add Print

Question

I've just implemented a share-button, that has a share menu:

 [_shareButton sendActionOn:NSLeftMouseDownMask];

And has this action connected:

-(IBAction)share:(id)sender {   
    NSArray *shareArray = @[@"testShare"];
    NSSharingServicePicker *sharingServicePicker = [[NSSharingServicePicker alloc] initWithItems:shareArray];
    sharingServicePicker.delegate = self;

    [sharingServicePicker showRelativeToRect:[sender bounds]
                                      ofView:sender
                               preferredEdge:NSMinYEdge];
}

Now to my question, I don't want Facebook and Twitter to be an option in the menu. I only want E-Mail and Messages to be available. Also I would like to add "Print", but don't know if I can do that.

Is that possible?

Thanks

Solved it by using proposedSharingServices.

- (NSArray *)sharingServicePicker:(NSSharingServicePicker *)sharingServicePicker sharingServicesForItems:(NSArray *)items proposedSharingServices:(NSArray *)proposedServices{

// Find and the services you want
NSMutableArray *newProposedServices = [[NSMutableArray alloc] initWithCapacity:5];
for (NSSharingService *sharingService in proposedServices) {
    if ([[sharingService title] isEqualToString:@"Email"] || [[sharingService title] isEqualToString:@"Message"]) {
        [newProposedServices addObject:sharingService];
    }
}
NSArray *services = newProposedServices;

NSSharingService *customService = [[NSSharingService alloc] initWithTitle:@"Print" image:[NSImage imageNamed:@"PrintImage"] alternateImage:nil handler:^{
    // Do whatever
}];

services = [services arrayByAddingObject:customService];

return services;

}
