TN Transaction Analysis column Alias bs

Is it possible to get a custom Document Attribute to display in transaction analysis with an alias. For example the field result is passing through the TN I can successfully get the result displayed. However the result is a 1 letter value. I would prefer if i could get the result to be displayed as text. So i would need something like P is the value and “Successful Transaction” to be the displayed message in the result column.

The only way i can this to do this is to have the IS construct the message and add it to the XML and pull the text as a new column?

is there a way to use alias’s or something? Processing rules that adjust custom attributes?
