Formula Tool Enhanced Data Preview Functionality

[Dav33054]

Anytime you create a formula in the formula tool, you get a data preview based on the values in the first row of data.  However, if you have a complex "IF c THEN t ELSEIF c2 THEN t2 ELSE f ENDIF" formula then the data combination that gives a TRUE result will likely exist on another row.  Therefore, you need to run the workflow, or place a filter tool upstream to isolate the specific row, to test if the formula result is correct.  

It would be easier if you could select the Input anchor of the Formula tool, then filter the data in the results window to isolate the row in questions, then the data preview would be based on that filtered data set.  I believe this would save a lot of time in the workflow development phase.
