MT4's default Equidistant Channel doesn't have a 50% line?

Hi everyone,

As we all know, MT4 does include an Equidistant Channel drawing tool. Unfortunately, it lacks any options to add additional levels/lines, for example a parallel at 50%.
Does anyone know any alternative way to solve this problem?

I'm still looking for this..can anyone help?

To recap my problem: I want to draw channels, but the standard Equidistant Channel drawing tool in MT4 doesn't have a 50% Midline, which I also require.
Does anyone know of a solution? I know there are scripts/indicators for MT4 that can create modified Andrew Pitchfork's..so I'm curious if there is a solution.

Something like this (see screenshot below).
Important: I'm not looking for an indicator that draws channels automatically! : )
