Question on fountain fills

Hi Everybody,..
Is this feature for Fountain Fills present in DRAW.   It's present in Photopaint.
For instance, in the linear fountain fill below, I would like the last marker to be transparent.  The fill would then fade to black in this case.   I could not get it to be transparent by dragging the empty icon from a palette or by using the property bar.
In this particular case, I could make the last marker to be black to mimic the background.  But then I would have to constantly change the last marker as the background changes.

Am I missing anything.
