@chain at element level?

Does @chain have (or can it be given) the equivalent of Pipe’s dot pipe .|>
I know you can use transform with ByRow, or vectorise a function within a chain block, but it would be very nice to just drop to element level the way you can with @pipe

Example

df = DataFrame( A=[1,2,3], B=[4,5,6])

#with @pipe
@pipe eachrow(df) .|> 
    begin
        sumAB   = _.A + _.B
        diffAB  = _.A - _.B
        (; sumAB, diffAB)
    end |> 
    DataFrame


#with @chain
@chain df begin 
    eachrow              .          #"." indicates pass at element level  - like .|>
    begin
        sumAB   = _.A + _.B
        diffAB  = _.A - _.B
        (; sumAB, diffAB)
    end                                 # no "." so pass at aggregate level, like usual 
    DataFrame
end
