KZZ2 trx - Possibility to do a massive updating of % overhead

Hello,

we have to update a very large quantity of new % overhead in costing sheet for cost estimate using transaction KZZ2. We did this activity manually in the past, but it's very heavy and it can cause errors, so we would like to know if there is the possibility to udpade them in massive way for example udpdating directly a specific table or something else.

Many thanks for support and suggest.

Regards
