Copy/paste shapes between OSC wave and LFO

2 things:

i can copy a LFO wave and paste it into the OSC wavetable window
cool
i can create a 2nd keyframe in the OSC wavetable editor and set the
wavetable editor’s “playhead” accordingly over the 2nd keyframe
copy another different LFO waveshape
paste it into the OSC wavetable
but: it will not paste as a 2nd wavetable but override the whole…

i can copy LFO and paste into OSC wavetable
would imho also be cool the other way round:
create a shape in the wavetable editor, copy it
and paste it into the LFO window
