YTA description scraping for mass uploads?

I know YTA has a description scraping feature but how do I set it up to mass download/upload with the correct descriptions?

YTA didn't work well for me in regards to this very aspect (scraping + downloading) while doing a pretty good job at each single task, so I eventually had to write my own bot.

Not sure if there's an effective way to do it, maybe in one of the new updates. You might maybe ask Arby. HTH!
