Sorting based on selection order in VizLib Custom Report Table - New Feature Request

In a Vizlib Custom Report table we need a sorting functionality where we can sort a column in an order which user has made the selection

For eg : In a Custom Report table we have a column called Product and records are A,B,C and D. We have same field as a filter.Suppose if a user is selecting (B,C,A,D) then in table we need to sort it in this specific order (B,C,A,D) and  If user selects A,D,B,C then we need to sort in this order( A,D,B,C ) 

Can you please check the possibility of getting this functionality added to the VizLib Table?

Thanks,
