inspection lot for production order lot and not for single pieces

Dear all,

I have a production order , for example, for 12 pieces / serial number . Material is produced in lot , in this case 3 lot of 4 pieces.

Pieces in a lot are linked toghether in a grap.

Production order create an inspection lot where I can store quality data for every pieces / serial number.

I need to store quality data at lot level ( for example the grap weight );

Is it possible ?

Regards
