Uploading many files to FTP/SFTP using a temporal name

Hello,

I am trying to upload several files to the same server.
I need to use a temporal name during the transfer and only rename the file once the transfer is completed.

Transferring a single file worked fine using a batch file like:
  insecure
  no-progress-meter
  user = "fulanito:Secret"
  ftp-create-dirs
  upload-file = "/path/to/workdir/file_0.txt"
  url = "ftp://ftp.example.com/target/folder/file_0.txt.tmp"
  quote = "-RNFR target/folder/file_0.txt.tmp"
  quote = "-RNTO target/folder/file_0.txt"

The problem is when we try to upload two files:
  insecure
  no-progress-meter
  user = "fulanito:Secret"
  ftp-create-dirs
  upload-file = "/path/to/workdir/file_0.txt"
  url = "ftp://ftp.example.com/target/folder/file_0.txt.tmp"
  quote = "-RNFR target/folder/file_0.txt.tmp"
  quote = "-RNTO target/folder/file_0.txt"
  upload-file = "/path/to/workdir/file_1.txt"
  url = "ftp://ftp.example.com/target/folder/file_1.txt.tmp"
  quote = "-RNFR target/folder/file_1.txt.tmp"
  quote = "-RNTO target/folder/file_1.txt"

That we receive an error:
(21) QUOT string not accepted: RNFR target/folder/file_1.txt.tmp

Looking at the documentation of the "quote" command it seems that all the quote commands (with -) are sent after each successful transfer.
This means that after transferring the file_0.txt.tmp CURL sends also the commands to rename file_1.txt.tmp and fails.

I tried to use the "--next" option but it seems it reconnect each time to the FTP server (at least we need to give again the user credentials)

The only workaround we have found is to use "-*RNFR" and "-*RNTO" so the fails are ignored, but

How I can do that curl applies the quotes only to the last defined url? I am thinking in something like a "--blockquote" that group quote commands with the last defined url, but I might be completely wrong and the solution goes in a completely different direction.

Thanks!
