Multiple entries in categories

Hi all.

Is it possible to quickly enter the same sub categories under a number of master categories?

Before the latest category structure it was possible to have top cats as:

Windows SBS 2003
Windows server 2003
Windows server 2000

with

operator error
system error
hardware error

as the sub categories. All of the top categories could have a pick from the same sub category. Not idea (the current structure is much better) but useful for certain entries that need to be available in each sub category.

Now we have to enter the sub categories under each top category so in the above example nine entries are required..

Expand the top categories to maybe sixty and it is getting a bit long winded.

So can we have "master sub categories" for those items that are always a possibility, particularly "operator error" or the ability to auto propagate a sub category across all/selected top level categories?

Thanks - Terry
