Wave to LFO designer feature request

small portion of the sample (e.g. single cycle waveform) could be sent to lfo designer to make the process of creating the custom lfo less cumbersome, and would allow for phase adjusments of the lfo, which is absent atm.
even better would be some controls for the manipulation of the waveforms that the lfo uses (morphing between waveforms, phase adjusment or whatnot)

just an idea.
