Mass update records through Portal iViews

Hi experts!

Is it possible to perform mass updates (updates of multiple records in parallel) through Portal iViews?

The Data Manager enables you to select multiple records from the record list and then update one or more fields common for all the selected records. As far as I can tell the Item Details iView only supports one record, but do you know how mass update could be solved in the portal iViews?

We are currently on MDM 5.5 SP06 Patch4.

Thank you very much!
