Vendor Lot Number for non batch management materials

Hello SAP Gurus,

We had some products which we set up without batch management but now for audit purpose we need to add vendor lot, date of manufacture, and Best by date while doing MIGO.

We have asked to activate batch management for these products but their quote is super expensive so we can't some easy solution. May be we can use customize field or misuse existing fields. My question to you guys - Is there any way to just show vendor batch field? Also, if you guys suggest any fields where we can add three info about batch and dates.

Thanks in advance.
