Hi @mohsin-raza 

You can utilize Index column, one way to do, if you have a lot of values to add according to the Index, you can utilize a custom function like switch

[a=Number.RoundTowardZero(([Index]-1)/10),
b=if [Index]=1 then null 
else if a =0 then "A" 
else if a=1 then "B" 
else "Unknown"][b]
