How to include exposed filter name in views data feed export CSV title? Trying to get views data export to save file with selected token from exposed filter

In the settings I can see this explanation:

%exposed == effective exposed filters, like filter1_foo-filter2_bar

So I tried this:

%[field_industry_type].csv                    
%field_industry_type.csv
%field_industry_type_tid.csv


But can't get nothing to work, what I'm trying to do is use a field filter as .csv name, one of the filter types is industry, so if industry is "relocation" I would like the file to save like this:

relocation.csv

Maybe my token syntax is wrong?
%exposed itself combination of the number of exposed filters you have on your view. When you save file name only with %exposed.csv it should generate file name as per your request would be like "industry_relocation.csv".

So, %exposed will generate based on "FIELDIDENTIFIERNAME_VALUE-ANOTHERFIELD_VALUE". 

To generate a custom file name you should use hook_views_pre_build() function. You can find examples here: https://www.drupal.org/project/views_data_export/issues/1288612
