Currently the subproducts feature is very inefficient in that editing / deleting subproducts is a manual process and takes too much time.
Ideally, the subproducts can be changed or deleted if an SKU is removed from the subproducts list.
Example 1: 9781455829132|9781455829156|9781455829194 --> 9781455829132|9781455829156
The SKU 9781455829194 would be removed from its subproducts.
Example 2: 9781455829132|9781455829156|9781455829194 --> (all SKUs removed)
All subproduct associations for 9781455829132|9781455829156|9781455829194 SKUs would be removed.
