Orchestrator: Not possible to pass a list variable into a Report's data selection?

Hello,

in an orchestration I want to pass a variable like ${listOfValues} into a report's data selection like

However, I was not able to achieve that, no matter how the variable was defined/formatted, for example

listOfValues (String) = "value1, value2" or "value1|value2"

(The reports executes ok but does not select any data)

I only can pass variables holding one value each.

That works. But that does not help me, since the number of values (aka the lenght of the list) I need to pass, varies.

Is that not possible to do from the orchestrator?

Thanks in advance.

(I worked with report R46171, although the problem seems not to be report specific, but a general issue.)
