Get the suppressed values

Hi all, I want to get the suppressed values from the output of the concat function.

The mapping looks like this:

Constant ->

Fieldvalue (x3) -> Concat -> destination (x3)

The Valuefield has a queue with 3 values, but after the concatination, the last 2 are suppressed. How can I get them? The first "destination" node gets its value, but the last 2 nodes dont.
