Power Query Records access record filed in let statement,

[Dicken]

Hi,
I have what I wanted as far as result but I think it may be better written,

So within a let statement I wanted to get the record field values if TRUE so below produces true / false column

 Table.AddColumn(A, "Custom", each [ One = [Item] = "A" , 
                                                         Two = [Item] = "B", 
                                                         Three = [Item] = "C" , 
                                                            Four = [Item] = "D" ])

This below gives me true and false that I want, but it means typing it all out each time I want to use it in a step

     Table.AddColumn(A, "Custom", each [ 
                                                              One = if [Item] = "A" then 10 else "FALSE", 
                                                                Two = if [Item] = "B" then 20 else "FALSE" , 
                                                               Three = if [Item] = "C" then 30 else "FALSE" , 
                                                                     Four = if [Item] = "D" then 40 else "FALSE" ])

Since original post I have got a result but if any one can suggest a neater / shorter way of wriing it plase let me know, I would like to use the 'one , two, three, four ' form the original records, but not sure this is possible. I will attach copy;

This code i have is ;

 let R = 
                                  [ One = [Item] = "A" , 
                                       Two = [Item] = "B", 
                                     Three = [Item] = "C", 
                                          Four = [Item] = "D" ] , 
                            R2 = 
                                           [ One = if Record.Field( R, "One" )   then 10 else Record.Field(R, "One") ,
                                       Two = if Record.Field( R,"Two" )       then 20 else Record.Field( R, "Two") , 
                                         Three = if Record.Field( R, "Three")  then 30 else Record.Field( R, "Three") ,
                                           Four = if Record.Field( R,"Four" ) then 40 else Record.Field(R, "Four") ] 
                                   in R2
