Calendar view - changing fields used to draw task bars

[js63]

Hi everyone..

Is there a way to change the fields used to draw the task bars on
Calendar view from "Start" and "Finish" to something like "Start 1"
and "Finish 1" instead?

I don't like how MS Proj automatically calculates Start and End dates,
as it doesn't reflect how I manage the project. So, I have Star1 and
Finish 1 that I use instead. I was able to change the Gantt chart to
use those to draw it's bars, but I can't seem to find a similar option
for Calendar.

BTW, this is for Project 2003.

Thx..
