As far as I know this feature isn't available in the september release too.
So for now I just do
- the selection in QlikView/Qlik Sense
- select the excluded values
- concatenate the values comma-seperated.
- save them in the import-excel / filters
- import the excel through import tasks
Not very convenient as this doesn't work dynamically but at this time it's the best workaround I've found.
