Not currently, but that's a great idea for a future version.
What you can do in the current version is browse files via Settings > Add Files and tap the download icon that appears next to each video to quickly queue up multiple downloads.
Awesome, if you could add these to your feature requests that would be great!
Thanks for the workaround, that sounds much easier than what I've been doing so far.
Please pass along to the team my thanks, this app is great and I look forward to using it throughout 2018 too!
