Bulk signing timeout makes this task sign files that were already signed

[MaxDeBy]

I try to sign around 70 files, give or take. If there is an error during signing, which according to the error I get is most likely a limit set by the timestamp server, this task waits for the time specified under "Delay in seconds between signing actions per provider requests". And then tries another attempt at signing EVERY file. But that's just going to cause the same issue, except maybe once if you're lucky.
Maybe I understand it wrong but that's at least what the log tells me. Wouldn't it make more sense to just wait between each file for the time specified or if it fails to only attempt and sign the files that have not been signed yet?
