[Koha] Import Records - Inventory Number

Hi guys, i have to make an import from a file where i have a lot of MARC21 records. Is there a way to autogenerate the inventory number for each one of those record when they are imported? (The inventory number is just numbers 1,2,3,4,...,n) Is the inventory number the field 952 $i? Thx! Saludos Cordiales.
