I have been trying to bulk update sheet formats but have noticed strange behaviour with the automatic borders.

In my system, by default the automatic borders are set to a level called "ZONES" in document properties and the line thickness is set to 0.25mm.

When I reload a sheet format all the other items in the sheet move to the correct layer but the Automatic Border doesn't.

It seems to ignore the setting in document properties and resets to the border layer to "-None-".

I now want to reset it back to "ZONES" but as the automatic border is configured through a program "swCommand_Border_Editor" I'm wondering if it is possible to set this layer via API as I can't find any commands to do it?

Any ideas would be appreciated.
