I am setting up an RTMC screen with some alarms. I am using the expression builder to reduce the data from its raw form into a consumable form. Under my present strategy I have to manually enter in each of the constants into the expression builder. I would prefer to reference an external data source (excel file, toa5, etc...) that had these constants in there. This would make changing things in the future very quick. It would also make error checking and QC a lot easier.
Is there a way to do this? Am I reinventing the wheel?
