Submit document blob path to Azure Document Intelligence service?

Question

I'm using the Azure AI Document Intelligence Python SDK (azure-ai-documentintelligence) to analyze documents stored in Azure Blob Storage. My current workflow involves:

1. Downloading the document from Blob Storage to my application
2. For large documents (100+ pages), splitting the PDF into chunks in memory
3. Sending each chunk's bytes to the Document Intelligence service

Question:

1. Can I pass an Azure Blob URL directly to begin_analyze_document for single document analysis instead of downloading and uploading the file bytes? I'd like to provide a blob URL (with SAS token or Managed Identity) and have Document Intelligence fetch the document directly.
2. Does the service support page range parameters (e.g., pages="1-100") so I can analyze specific pages without splitting the PDF myself? This would allow me to process a long document in ranges without downloading/chunking.
3. Is there a single-document equivalent to AzureBlobContentSource used in batch processing? I know begin_analyze_batch_documents supports blob sources, but it seems like overkill for single document analysis.Is it possible to directly pass the Azure Blob Storage URL/path to the Document Intelligence service instead of downloading and uploading the file content? I want to avoid the intermediate step of fetching the blob content to my application before sending it to Document Intelligence.
