Formula Tool: "Current Output Column" Variable

[AlteryxUserFL]

I often encounter situations where I need to apply the same formula to several columns. Doing this requires copy/pasting the formula several times  and then updating the variable names in the formula for each output column. I wish there was a built in "Current Output Column" variable so that I could build one formula and use that for each column. 

For example:

@AlteryxUserFL I agree that this would be useful! The multi-field Formula can help if the formulas are all the same, but I still would like to see the [_CurrentField_] added to the regular formula tool.
