VCS Labeling for Multiple Directories

I am currently trying to enable VCS labeling with SVN. I am having some troubles getting this to work. Currently I am trying to label a source that has this structure.

- trunk
- dir1
- dir2
- dir3
- dir...

In my checkout rules I have:

+:dir1
+:dir2

as I only want/need those two directories. In the VCS root I have:

dir1 => /tags
dir2 => /tags

but it is telling me they cannot both go to the same directory. The output I would like to have is

- tags
- {labeling pattern}
  - dir1
  - dir2

Is there any way this can be accomplished? Is there another way I should be approaching this?

Thanks!
