There is no other way. The system does not allow you to rearrange file data
on the disk. You can read and write, extend, and truncate, and that's it.

I've written software that uses linked lists of data arranged throughout the
file. The application that does this, in effect, allows the user to insert
data items at the top of the file. I can offer thoughts on ways to do this.
But display of the data is controlled by the program. If you want to produce
a regular text file that can be read by other programs, you'll need to write
the file exactly as you want it to appear.
