Commerce - Custom transaction log possible?

[Tom Christian]

I'm creating a code hook that extends the \IPS\nexus\Invoice class and save() method. Once the invoice is set to paid, I'm running some custom code. At this point, I'd also like to create a transaction log to appear within the nice little "Transaction History" block. Is this possible?

	public function save()
	{

		if ( $this->status == \IPS\nexus\Invoice::STATUS_PAID)
		{

			// create log here

		}

		return call_user_func_array( 'parent::save', func_get_args() );
		
	}
