Add "sort by completion date" option

[LizaFarr]

In the Workforce Dashboard, I don't see any way to sort the list of assignments by completion date. My crew does not necessarily complete work orders in the order they receive them, so sorting by due date doesn't help. I can't tell what my crew has completed in a given day without clicking on every single completed assignment and checking what day it was completed. If I could sort the assignments by completion date, it would solve this problem! Thanks!
