Creating a category be only link to other category

[abc500x500]

Hi
At first i thanks you for developing Osclass.

When we use OsClass as YellowPage we find problem.

See these sub categories:

1) Repairing--->Automobile
2)Automobile--->Repairing

or
1) Shop -->sport shop-->Bicycles
2) Vehicle-->Bicycles

or
1) Security--> Secure Camera
2) Shop--> Electronic Shop ---> Secure Camera

As you see if we want creating ads or information in those sub categories we must copy ads in 2 or several sub categories.

It is very good if you insert this ability:
CREATING A CATEGORY that ONLY is LINK to OTHER CATEGORY.

I see this ability in some forum software for example PHPBB.
In phpbb we can creating a forum that only is a link to another category.

Thanks
