Is it possible to change or correct data using migration cockpit(LTMC)?

Hi Team,

In my new project I would like to use migration cockpit LTMC.

The problem I`m facing is, I know that I can upload new entries. But is it possible to change the entries already uploaded?

For eg., I have uploaded 100 new entries from legacy to S4 Hana. But after few months would like to change or correct the uploaded fields. So in this case, can I use LTMC for updation?
