Folder acquire

Hi,
I've an organization with two "x" folders under two different folders ("a" and "b"). So
```
Org
|
|- a
| L x
|
|- b
L x
```

I've written the following deployment to acquire these resources:
```
- name: x-a-folder
type: gcp-types/cloudresourcemanager-v2:folders
properties:
parent: folders/123456789012 # (a)
displayName: x
- name: x-b-folder
type: gcp-types/cloudresourcemanager-v2:folders
properties:
parent: folders/123456789013 # (b)
displayName: x
```

And I have the error:
```
$ gcloud deployment-manager deployments update resources --config resources.yaml --create-policy=acquire
....
- code: RESOURCE_ERROR
location: /deployments/resources/resources/x-a-folder
message: '{"ResourceType":"gcp-types/cloudresourcemanager-v2:folders","ResourceErrorCode":"404","ResourceErrorMessage":{"statusMessage":"Not
Found","requestPath":"https://cloudresourcemanager.googleapis.com/v2/x-a-folder","httpMethod":"GET"}}'
```

In this case how can I say that I want to acquire two resources with name x but that in deployment must have a different name? An optional ```name``` field is not considered by DM

Thanks
