macro extract defined function name

I have two functions

funcA(x::AbstractMatrix;subd=nothing)=funcA(x[1,:],x[2,:],subd) # format transformer
funcA(a::AbstractVector,b::AbstractVector;subd=nothing)
    babalah
end

and

funcB(x::AbstractMatrix)=funcB(x[1,:],x[2,:]) # format transformer
funcB(a::AbstractVector,b::AbstractVector)
    babalah
end

I wish a macro can easily help me to add the "format transformer" automatically to the funcA and funcB and it can add arguments. What should I do?
