Macro for Precipitation?

[BadBlake]

I finally got BI Tools working again but can't see how to create macro for precipitation. Can't see it here in BI tools -only precipitation rate. Anybody?

Here's the BIT Help file ==>> here.

In my BIT, "precipitation.txt" is assigned to %4, however IIRC, you should be assign any value in a text file to any of BI's unassigned macros.
