Order Query > Items > BundleComponents > Sku

[Dan Gill]

I am currently able to query orders that match a SKU:

$filter=Items/Any(c: c/Sku eq '718721999465')&$expand=Items($expand=BundleComponents),Fulfillments($expand=Items),CustomFields

I am struggling to find a way to query Orders based off a matching Bundle Components > Sku? Is this possible?

Thanks, 

Dan
