Try as I have, I've not been able to do an export via exportSession:doExportOn[New|Current]Task method and include exportFilter in the export session's export settings. It would be useful to be able to do that. For example, my plugin ExportManager which allow one to start multiple exports at the same time (or back-to-back) - if user specifies an export preset that includes export filters, the export filters are ignored. Also web outputs which create multiple exports (for thumbnails and main view as example), can not use export filters for the various copies, since exporting of said copies is done via the aforementioned method. If I'm wrong, and there is a way - please advise.
