Customer consignment stock view not available at Ship-to party level

We have moved our stock to customer consignment stock using order type KB (Consignment fill-up). When we view stock situation using MB58 (Consignment at customer) the stock shows up under customer sold-to. However, we would like to see how much consignment stock do we have under each ship-to location. Is there any view or report in the system which shows consignment stock at each ship-to level?

We have tried the following:

1) We thought of making ship-to party equal to sold-to party thus using the same output (MB58) but we have several ship-to's (sometimes 50) per sold-to which will make sales analysis and pricing maintenance difficult (as our pricing is based on sold-to).

2) We looked at table MSKU (Special Stocks with Customer) and in it stock is stored at the sold-to level and MB58 pulls out stock from this table only. We thought of using user exit to move ship-to number in MSKU table at the time of stock movement but then we will have to change ATP logic (user exit again) also for consignment issue orders and we would like to avoid all that in case there is a simpler solution.

This seems to be a requirement which lot of customers would have, Are we missing something obvious. Please help.
