Rule Engine (Dictionary): Add option to keep input of replacement column

Feedback & Ideas
1

Hi,

Scenario
very often I use the Rule Engine (Dictionary) for complex data matchings. However, if not matrch was found, the value in the replacement column get removed.

Problem
This requires either a separate rule to be appended, another column to get appended and merged with a column merger or another rule engine node to conditionally replace/keep.

Suggestion
In order to simplify the usage of the Rule Engine (Dicionary) node, I’d like to propose adding the option to keep the values from the replace column as a fallback.

indeed, something like support for "TRUE => $$CURRENTCOLUMN$$ would be nice to have because otherwise you lose a lot of the dynamic nature of this node

or a simple checkbox “retain column value if no rule matches”
