Asset automation change used by field with a custom field from requester/agent

Hi all,

We have a difference in domain login and used by field on the asset, which we discover through the agent. We use the domain sync of the fresh service probe from the accounts. Now the automatic asset mapping does not work.

1. We've added the AD sAMAaccount as custom field on the profile, which is now visible based on the custom mapping
2. We would like the update the asset, based on a match between the new custom field and last login field on the asset. With that match we would like to update the used by field and department field

Any ideas how to build this in the automation?
