Hierarchy order

Hi,

We have a location hierarchy in the system which is order by the following:

1

112

121

2

22

312

That's what we see in the single hierarchy drop down box.

Is there a way to change the order by store number? like 1, 2, 22, 112, 121, 312....

I have tried to re-load the loc hierarchy with the order we want, but still not in the numeric order after the load.

Thanks,

Steven
