Hi, I think "Expressions" are based on one way traffic. Data collected from source elements will be considered for further processing. Any end result from the expression cannot be send back to the source elements. Once you type the new value for expression based defined property then its get converted to "custom value" and the "expression" gets override. Setting back to "Default" will collect the information from the source.
