Splitting a compound path out into multiple paths

[Geoff Harper]

Hi I'm trying to figure out the simplest way to split a compound path. 

I have a simple case illustrated here http://sketch.paperjs.org/#V/0.12.18/S/pZHBCsIwEER/JcRDFYqkSi8RD9ofED1aDzFdbWi6W9qooPjvplgVPBVd2MPM4c0Oe+OoSuCSbwpwOuch15S1WhM2jmkqKzphxuYM4cKSTq6Uy4e3FJmfg7E2IUu1ZMFAiEMQfvz1yYK34QxIWRakeB+lmOKTXYN20aIjt8Tx2jsKjxZe7Ioa4wyhZNsoFqHfXUdvzNWTp0J0ulI1oJPvg8M2a/YVtvwrrDX7h016N4t/aeYfta9BFRUZdA2X2939AQ==.

The ideal result is rect1 becoming its own compound path instance and rect2 becoming a different path instance. I know I could probably sus it out eventually doing a bunch of hit tests and what have you but I'm wondering if there's a simpler way.

Thanks
