As per my understanding you are extracting data from more than 1 country or more than 1 datasource ,So you can do one thing..........
Make different types of Qvd Generator to pull data from various datasources .This qvd generator will make qvd in a common folder (QVD ) then you can give path into your applictaion for this common folder to relaod data.
example : suppose i am having data base from 4 different type of location and erps
make 4 qvd generator for 4 different databases and give the common name in all qvd generator to pull data
then you can use this comon folder to relaod your data.
this approach should work or let me know.
