Are custom Stroke Shapes/Profiles possible? - for Spirals

[dvector]

Hi I have a problem, or at least I don't know a shortcut for this. I need to re-create aprox 30 spirals all expanding out to different line widths.

What I really want to know is there a way to specify the start point width and end point width of a line? especially the Stroke /Pressure profiles?

Thanks for any help.

PS I have used the handy SPX Spirals for Xara to generate a perfect spiral for cloning
