Writing an import utility with ChangeSetItem_CopyBranch

While writing an import utility to populate Vault from my previous SCM, I have been attempting to follow Eric Sink's methodology of installing all file-modifications in a folder called trunk and then, to create branches using ClientInstance methods GetByLabel_GetStructure and then to Commit a ChangeSetItem_CopyBranch, which MOSTLY works.
The problem with this is that the entire structure, and ALL files are duplicated within the newly created. However, I am looking for ONLY those files which also have the given LABEL as well.
Is there any way to do this? Short of deleting files, following the ChangeSetItem_CopyBranch?

Sorry, also, can you please describe the labelSubItemPath parameter to
GetByLabel_GetStructure.
I am wondering if I can somehow use this parameter to help me.
thanks,

Branches are designed to hold all items that get branched, not just the items that will change. The benefit of structuring this way is that a get of the branch will get all files needed for that branch to be built.
The normal way of achieving the desired workflow:
1. Code in trunk up to the release of version 1.0.
2. Branch 1.0 to $/branches/1.0
3. Code 2.0 changes in $/trunk, any subsequent edits to 1.0 go in $/branches/1.0
4. When you need to release 1.0.1, Label $/branches/1.0.
5. If you need to code 1.0.2 features, code them in $/branches/1.0.
By labeling each release, you are still guaranteed to be able to get the code as of any certain release, but you don't necessarily need a full branch for each 1.0.x release.
So as you're importing your (PVCS?) data, branch the first time that you see a 1.0 label, and apply edits for all the changes off that label.
As for your specific question, if you choose to go that route, it is possible to call copybranch on a file-by-file basis to customize your resulting overall branch.
