SOPC generate and NiosII symbol look

After editing in SOPC and Generating and updating the NiosII symbol, I find that the edited modules are sometimes in a different location on the symbol than they were before. What determines where they will appear? Short of manually editing the project bdf or NiosII bsf after every edit, is there any way I can control this?

    The ports on the symbol are added in alphabetical order... so "sdram_foo" as defined in SOPC Builder will have ports below "sdram_apple".

    The exception to this is peripherals on a tri-state bridge; these will go into the bsf file in accordance with the name of the tri-state bridge. For example "ext_ram_bus", and all the peripheral ports associated with it, will come before the two SDRAMs I described above.
