Moving pCell Layout to 0:0 Origin

Hi, 

    I just created a pCell and it's doing everything it's supposed to do. However, I've discovered that the origin of the pCell in the layout is not at 0:0. This creates minor issues as when the pCell is instantiated and placed in the layout, it's inconvenient for the user to align it with existing shapes. Is there a way in SKILL to move the pCell origin to 0:0 without having to rewrite a significant amount of code? Since this is a pCell, I'd like to avoid using le commands. 

Regards,

Nishant

    I know that in AEL (used in ADS) there's a nice convenience function called deSetOrigin() which sets the origin for your pcell after you've coded everything (to force the origin of your pCell layout to 0:0)

    Well, there's a convenience function in SKILL too, leMoveCellViewOrigin, but it's not intended for PCells. The assumption is that in PCells you think about the coordinates as part of the design process, but adding the loop I mentioned previously is easy enough too.
