How can I stop Symbolics.jl from splitting complex numbers into real and imaginary parts

General Usage

For some computations it is useful to keep “conj(z)” as it is.
For instance:

julia> using Symbolics
julia> @variables z::Complex
julia> z*conj(z)
real(z)^2 + imag(z)^2

Is there a simple way to obtain “z*conj(z)”?
Thanks
