GPO to map drives conditionally

I'm not sure if this is exactly what you are trying to do, but I recently moved from a script to map network drives to using Group Policy Preferences to do this. The level of control and automation is incredible. Here is the Microsoft "Getting Started" link. There are a ton of references on the web that go into greater detail about the types of things that you can besides just map drives.

We have different shared drives for different departments, and some people should have access to multiple drives. GPP allows us to assign the drives to specific Organizational Units, Security Groups, or pretty much any level of targeting that you can imagine. This greatly simplifies setting up new computers for users.

We also use this for Shared Printers, if that is something you do as well.

Some issues that we have run into, Windows XP machines must have a few prerequisites installed before they can process the GPP. We also had to set each mapped drive to "run as the logged on user", to ensure that the proper permissions were set so that the drives would actually mount.

This could be an alternate route around your problem, while at the same time, providing a more "visible" method to administer these shares.

You should use Group Policy Preferences drive mapping in replace mode and do item-level targeting to only apply the mapping to whatever group you want.
