When you work with your Sample Requests via the Dashboard you can Bulk update some of the values.
Per state of the Sample Request you can select one or more sample requests and update them to a new value.
Just set a check mark on those Sample Requests you want to update.
That will make a pop-up window appear with the values you can update for Sample Requests in this state.
Once you have set the new value - remember to click on "Update"
For all states it is possible to change the state of the Sample Requests - the example here is for Sample Requests that are in Planned state.
For all Sample Request - except those that are in Planned state - you can also Bulk update the approved field. This will set the entire Sample Request to Approved.
Just set a check-mark in the Approved check-box and click on "Update".
