RudiC, I don't think he's trying to parallelize the upload, just send the first tenth without waiting for the computer to finish processing the last tenth.
Step back a little. Why are you using rsync to send 10 files? What exact problem is being solved by splitting and transferring the file this way? Is your connection unreliable?
I don't think you can "trick" rsync into using incomplete files, you may need to arrange something else. It may be possible to avoid splitting the file at all!
What kind of connection do you have between yourself and the destination? 2 tb in 2 days sounds pretty fast. Are you on the same subnet, even virtually?
What's your operating system? On Linux, I think you can use losetup to create a device that's a "view" into a file on disk. So instead of creating a 200 gigabyte file, you'd just create a device which maps to the first 200 gigabytes with no copying or fuss. Whether rsync will swallow loopback files remains to be seen.
If you don't need to use rsync to transfer, you can just grab sections of file by any means you like and transfer them without writing the split file to disk at all.

atrm(1) General Commands Manual atrm(1)
NAME
atrm - Removes jobs spooled by at
SYNOPSIS
atrm [-a] [-f | -i] [job_number...] | [user...]
The atrm command removes jobs that were created with the at command.
OPTIONS
Removes all jobs belonging to the person invoking atrm. If invoked by a privileged user, all jobs on the queue are removed. Suppresses
the printing of all information about the jobs being removed. Prompts before a job is removed; a response of y, or the locale's equivalent
of y, causes the job to be removed. Obsolete version of -a.
DESCRIPTION
If one or more job numbers is specified, atrm attempts to remove only those jobs.
If one or more usernames is specified, all jobs belonging to those users are removed. This form of invoking atrm is useful only if you
have superuser authority.
EXAMPLES
To remove job number 62169200.a, created by user chinn, from the queue created by the at command, enter: atrm chinn.62169200.a
Note that specifies an at job for sh. (.f specifies an at job for csh, and specifies an at job for ksh.)
FILES
Main cron directory. List of allowed users. List of denied users. Spool area. Queue description file for at, batch, and cron.
SEE ALSO
Commands: at(1), atq(1), cron(8)
Files: queuedefs(4)
