MergeAndCenterColumnHeaders in Cube Views

Hi,
Anyone on Version 8 who's actually tried to use this 'enhancement' feature in Cube Views?  We requested this on Ideastream a long time ago with a lot of support.

I can see this command is now available in the header format dialog; however, it would appear that the only thing it does is change the header from left justified to center view.  There does not seem to be a way to actually 'merge' column headers, despite the fact that it's called "MergeAndCenter".

Even the system documentation appears to confirm this behavior.

Someone please tell me I'm missing something here and it actually is possible to merge column headers, because we really really wanted this feature.

Thanks
