Pitchslide Command For Volume Column

Currently, as far as my eye can see, there are various effects in the Panning and volume column that can be used, such as retrig, cut, play sample backwards, volume and panning slide.

I miss the pitch-slide, some of the notes i would want to apply a pitch slide whereas others i would not do.
And since the volume column has some unknown effect commands in stock, maybe pitch slide up and down could be assigned to one of them.
I don’t know if this is hard to record when using pitchbend wheel on a MIDI device…
