Add New AutoCalculate Function
 

How can I add an additional function to the AutoCalculate menu in the lower
right hand corner. It's nice to have an automatic function such as sum,
average, count, etc. and I'm looking to add some more functionality. I have
tried the application.statusbar way, but that puts the function output on the
left, not in the correct box, as well as I have to enable the sub/function
before the first use.
