Allow Multiple Batch / Serial Numbers when Changing Costing Method

We have several thousand SKUs with existing stock which may have multiple batch numbers  or expiry dates per SKU.

Currently when changing the costing method of a product to a Batch or Serial method, Cin7 Core will ask for the Batch / Serial / Expiry of the existing non-zero stock.

However, it will only allow you to input ONE batch/serial/expiry for ALL the existing stock of the same SKU, whether you are changing the costing method from the product page or doing a bulk costing method change via CSV.

After reviewing this I was told by Cin7 support that the workaround for this limitation would be to change the costing method to one of the batch numbers, and then adjust the correct batch / serial numbers in via a stock adjustment.

However doing this via stock adjustment makes things several times harder, because you must find and re-input the received date / unit cost for every item you are adjusting in. This makes the process 3x more time consuming.

Please make it possible to input multiple batch numbers when changing costing method. The system might ask this per purchase order / item movement for a given SKU, and ideally let you break it down further as you may receive several different batches in one purchase order.
