Proftpd - how to upload first to a temporary folder?

Question

linux

Does proftpd have a setting to put files in the folder where the ftp user uploads them only after the ftp server has completely received the file?
For example, an ftp user uploads the file test.txt to /home/ftpuser/ , and we tell proftpd to accept the file somewhere in /tmp/proftpd/, and only after the file is fully uploaded to /tmp/proftpd/ , proftpd conditionally does
mv /tmp/proftpd/test.txt /home/ftpuser/
Or is there another way how to get valid and downloaded files in /home/ftpuser/ at once? Since the scripts that look into this folder work on the server, and they cannot wait until the file is loaded...
