Include a Result Column equal to Condition Condition

Hi there

Is there a way to have a Result Column that is equal to a Condition Condition in an Expression?

For eg:

Expression1

InputA     OutputB

01               Z1              

01               Z2

01               Z3

Expression2

InputA     OutputB

Z1               1001

Z2               1002

Z3               1003

Table

ColumnA     ColumnB

Z1               1001

Z2               1002

Z3               1003

Loop at Expression1; then execute Expression2 (multi level). This gives us OutputB - 1001, 1002, 1003. My Table has only the OutputB. I need to hold the value for InputA too. And I do not want to add another Output column to my Expression2 and repeat the data with InputA. Even though that would work.
