LSMW to change alternate labels for Functional Locations

We are going through a functional location restructure and will use the

alternate label functionality to achieve it.

If anyone out there knows of a standard SAP method to carry out mass changes to alternate labels please let me know.

Although individual change/create of a label is relatively simple using IL02, we have found that we can not do mass changes using OCX functionality, CATT uploads or LSMW. The problem is that the recording used by thesetools does not work (the screen used to select the label system to be changed

does not have a selectable field).

Any help appreciated
