Update all items in a sharepoint online list at once

[Filipe Matos]

Hello everybody,

How can I display a button in the command bar of a Sharepoint Online list that requests a date from users and uses the input value to update a specific column of all list items? 

I have implemented a flow with a power app dialog that already does that, but I haven't found a way to display it as a button at the top of the sharepoint list.

Thanks in advance.

I finally got it working.

the approach I have chosen combines a command set extension which calls a power app responsible for querying the user via a form which in turn feeds the output into a flow that updates the list items as required.

Might not be the slimmest solution and perhaps not conform to best practices but hey, it works 

Moving to the next step.
