title: Extend Collections Class VBA
body: <p>I have created a sort function to allow a collection of instances of a custom object to be sorted based on one of the objects properties. Is it possible to extend the existing collections class in VBA?  I do not believe inheritance is supported in VBA, so I am not sure how to go about this in the proper way. I could just create a new module and place the function in that module, but that doesn't seem like the best way of doing it.</p>
