Renaming Order Custom_0 to Custom_9 in Tessitura Analytics

We used the T_Order Custom Fields on the Custom Tab of the Order Screen for a variety of operational purposes for our Educational Programs.

It is very cool that this information shows up in Tessitura Analytics.

However, it is confusing to our users that the columns are called Custom_1, Custom_2, ....

Question:

Is there a way to change the names that show on Order Custom_1, Custom_2...

I did not see anything obvious in System Tables with a very quick look.
