For the MPS list to work like in 2011 and Prior (highlight exclude)

A customer of ours has upgraded from 2011 to Sage200c, they have gone to use the MPS list to select orders to exclude. This previously was done but Ctrl or Shift and clicking the individual orders then clicking Exclude - this then only included the highlighted orders. On newer versions this functionality was removed. I suggested a workaround to the customer to use filters in the workspace and tick the items to Exclude but it would be easier if this was back.
