How to add individual material id's in existing fixed assets

Hi,

I have created one asset for 100 laptops in past, which have only one individual material ID.

Now, I need to scarp one laptop which is broken accidentally. It become very difficult for me to process as ByDesign is going to scrap full value (all laptop) with single individual material ID.

Can you please let me know the possible workaround to scrap single laptop value or add individual material id which can be use for scrapping.

Thanks in advance
