Feature Types to NOT read Option in FeatureReader

I would like a "Feature Types to NOT read" Option in FeatureReader when using the single output port.

For instance, i'm using FeatureReader with the "single output port" parameter to read files inside a Zip file (i dont know filenames inside). But I would like exclude some files if they exist.

At the moment i'm using Tester to filter feature types (fme_feature_type_name on Schema port & fme_feature_type on Generic port) but data has been already read so its a performance issue.
