Update multiple records or copy/ paste records in Smartsheet Dynamic View


I am not sure if someone has raised this question before! But we currently use SS to track the projects at the company and also we've created some SS dynamic views for our partners for them to submit their updates to certain columns in the respective sheets! But they are finding it challenging to edit and manipulate multiple records at the same time since they have to use the form to update record by record. They are asking for same flexibility in the source sheet (i.e. copy/ paste). Also let me know if there is a solution for this rather than using the reports since they need access permission to the sources sheets.
