Hi @matt!
There are several eazyBI report examples in eazyBI Demo account. See for example Story points burn-down in selected Epic or Version report which are both similar to what you are looking for.
You can export these report definitions and import them to your account; and modify them with additional Sprint scope change measures.
Let me know how far you are with report builidng if you have some specific questions (more sensitive details or screenshots can be sent to our support mail).
