Give an option for scaling a tag via an expression directly from a read. Often I need to convert a tag from native units (deg C to deg F) or an odd combination of mathematical operations to convert the tag into the units/format desired. Currently have to do a direct tag read and then create another expression tag to then convert that "raw" value. Giving an expression option (in addition to the current, linear and other options) would eliminate a step and clean this step up and give much more flexibility to scaling.
