Proterozoic Template

Hello - looks like you created the Proterozoic template, very nice, but I was wondering if it would be possible to invert it so that the oldest part of the section is at the bottom?  That is standard practice in geology and is more common in these charts, since it allows the visualization of the "lower" and "upper" parts of the column.  I would do it but I don't think I'm smart enough with the syntax in these templates. If you have time, thanks in advance. Cheers
