Cosmos container with hierarchical partition keys can't be used as a dataset

We have some Cosmos containers (NOSQL) with hierarchical partitioning enabled which we want to use as a source and sink dataset in Azure Data Factory. When trying to create the dataset the following error pops up:

"Schema import failed: Error converting value \"MultiHash\" to type 'Microsoft.Azure.Documents.PartitionKind'. Path 'partitionKey.kind', line 1, position 366.\r\nRequested value 'MultiHash' was not found."

Are we doing something wrong or are hierarchical partitioned containers not supported as a dataset yet? If so, will this ever be supported? I can't seem to find anything about this in the documentation.
