Fabric Medallion - Unassign task

[KarenL7]

Please can we make it possible to unassign an item from a task in the medallion?   

Reason for this idea is that this is not currently available.  This was discovered whilst adding items into the medallion,  and a few were accidentally assigned and therefore no longer needed. 

It would be very helpful as we would like to assign other tasks but we are seeing tasks which are no longer relevant. 

Thanks
