Looking for a viable solution to mass update asset details

Hello,

We are trying to perform mass update on the following asset details:

1. Life Yr. Months

2. Location

3. GL Number

4. Category

5. Description

6. In Use flag

Currently business is using Asset Workbench to update the details on individual assets which is a tedious process for a longer list of assets, so we are trying to develop a process for our business to perform mass update of the above details. We did some research to see if there is any functionality bundled into EBS that would suffice our requirement but unfortunately we couldn't find a one for updating. We see there are multiple options to load and insert new assets but none for updating, so we thought of reaching out to Oracle and seek your help in
