Dash errors confirmed and download from specified file index question

[NoobishOne]

Confirm often errors with DashSegments!

Question: is it possible to fast-download from certain index position of file?
For my examples when it fails at 4000+ /12000 file, is it possible (or it is a request?) to download from this 4000 file, or next file.
-c (--continue) - doesnt help.
I know there is -i (ignore errors) attribute, but...
Filtering --beforedate helps a little, but again, youtube-dl cycles through all 4000 list from scratch with downloading meta and dash manifests for each - so its 10-12 minutes now, and more in perspective. So it good to have something like --startfrom 4122 so it fast skip 4121 lines from playlists pages.

Sometimes its pass OK, sometimes it fail on audio ( .m4a)
It was no errors until >4000 files (DashSegments appears)
My commandline looks like (if it matters at all):
youtube-dl -f "135+(140/171/bestaudio)/bestvideo[height<720]+bestaudio" -o "/YDK/%(title)s.%(upload_date)s.%(ext)s" >here link to videos page on YT< --restrict-filenames --verbose

Sorry for my english and all, first time submit )) Thx.

UPD: oh, i miss begining debug part ))

my comment about this problem now. I think it's important. every time I download a file from this error again, the segments downloaded in previous attempts are downloaded much faster and each time a file is downloaded more. but every time it is downloaded from the first segment, and it is a problem if large files!

I think that the downloaded segments cached somewhere. but the main problem is that it is necessary that such files are downloaded automatically. moreover, often have to start the download of the same file many times.

The interesting thing is that if you watch video that fails to download in your browser till the end. then youtube-dl will be able to download it.

I'm facing the same issue. Could you please tell in which update will this problem will be fixed? Thanks
