Expressions: Iterate over a list

I retrieve a list of objects in a microflow, when the list is not empty I will sent an email to inform the users of the found objects. 

The action to sent the email has an argument to set the text for the email. I want to text to be something like:

'Dear user, we found '+ $numberFound + ' objects' +

'The found objects are ' +

for(result : resultList) {

'$result/name '

}

Would it be possible to iterate over the list within the argument editor or do I need to create the result names outside this action and use that variable in the argument editor?
