markusslawik,
Thanks for getting in touch! When on any view, you can click on the ‘Export Listed Events’ button (screenshot) to Export the current view to an iCal file. We don’t currently have any type of ‘custom’ export functionality that you’re describing, but if this is something you’d like to see in a future release, I would suggest submitting it as an idea on our UserVoice page. Our team periodically reviews the most popular ideas for possible inclusion in a future release of the plugin.
Hopefully that helps to answer your question, but let me know if I can help further. Thanks! ๐
