Grid filter parameters to microflow

Hi ,

I want an customized export through an microflow , i.e not using the 'export to CSV' from mendix instead using the file entity from system. I have to write the content of a grid to the file and do an download. But i shld consider the filter parameters too from the grid . Since the page has to be single selection , i will not be able to pass the visible list to microflow. Is there any other way to pass the filtered list to an microflow else to get the filter parameters to microflow so tat i can do some list operation and get the list.
