Multi-Language/Localization of Paginated report

Hi Guys,

I am working on providing multi-language/localization function to powerbi & paginated report stack. I found a solution to translate the metadata of powerbi report but could not find full solution for paginared reports.

I have used User!Language string for my paginated report tablix title conversions but did not find solution on translating the parameter name. There is no option to put expression for parameter name. 

Also suggest if you have any other way of solving the problem of multi-language paginated report
