LFO retriggering

I am working (in Guru Sampler) on a kick drum with a kind of pitch drop using LFO/Pitch.  The LFO seems to be continually running even when I let go of the key.  The result is, the next key press may sound different because it is starting at a different pitch.  I am in mono/retrigger.  My request is to automatically retrigger the LFO on keypress when using mono/retrigger.  I understand it not working that way for polyphonic since the LFO is a single global across the patch and wouldn't make sense if playing legato either.

Please let me know if there something I am overlooking.  I've tried a few things and get the same result.  Or is there maybe a reason this doesn't make sense that I am overlooking?  Perhaps I will need to wait for Pitch EG.
