Support for Backblaze B2

[Mu0nDude]

I would like to use FileZilla to upload/download files to Backblaze B2. In some cases the files are large, ~100 GB or more. The information from Backblaze states:
You can find in the "Using Application Keys" section of this page: https://www.backblaze.com/b2/docs/application_keys.html
Use the new application key to get an authorization token that can be use to access the B2 APIs. Authorization tokens are only good for 24 hours. You can use the application key to make new authorization tokens as they expire.
You can resume uploading large files that were interrupted by the auth key expiring as explained on this page: https://www.backblaze.com/b2/docs/large_files.html

Can FileZilla cache or store my Application Key so that it can automatically make new authorization tokens to allow the upload to complete?
If it just pops up a window to re-enter the App Key, if I'm not there to enter the key I think the session times out.
With the large files I'm not always sitting at my computer waiting for the prompt!

TIA...

FileZilla Pro supports Backblaze B2, including long-duration transfer of large files. If a token expires during a transfer it is automatically renewed as long as the application key itself remains valid.
