Manual Batch No requires to be allowed same batch no for the different item

Hi All,
In pharma wholesale companies, surgical equipment comes with the same batch no with different variants.

For example,
Wheel Chair (S) - Batch No: 200
Wheel Chair (M) - Batch No: 200
Wheel Chair (L) - Batch No: 200

In ERPNext, each variant will be considered as a separate product so while creating batch for this product, the same batch number cannot be entered for the 2nd and 3rd items.

What is the right approach to enter the manufacturers batch number as it is.

Thanks in advance,
Regards,
Syed.
