Currently there is no option in d365 to edit record like Sharepoint online.

The only workaround right now is to use Exchange online feature, however it is still not user-friendly.

For now we can copy multiple columns with Power apps grid control but cannot update multiple columns.

Please consider adding new features in Power apps grid control or any other control to achieve that User can directly copy multiple columns in the first row and paste the value to the second row and update.
