Parse a parameter (macro) as a string in report

[mixim]

Hello Guys.
In our framework we have the following expression:

[Country].[Country_].[Country]  in ( #csv(split(',',$account.parameters.enterprise))#  )

This should parse a "$account.parameters.enterprise" parameter , and split it wherever there is a comma.
This is out of the box.

However, do you think its possible for me to create a report layer expression to view this parameter on the report itself?
I've been trying:

Code Select Expand

ParamDisplayValue('$account.parameters.enterprise')

But this is not working :/
