Azure AI Studio – Adding more files to an existing index through UI

Using Azure AI Studio, I create a data source and connections to azure blob storage. Go to Chat, select source and automatically create index. I select 1 time run, it indexes the data and I’m able to chat with it through the playground.

Please give detailed step-by-step instructions on how to add additional data (adding files to existing path or pointing to another blob path) and reindex it reusing the same index, preferably through the Azure AI or ML Studio UI, so it only updates the existing index without having to reprocess all the files.

Also please explain what happens if a schedule is setup instead of picking 1 time index, it reruns. Does it create a new version of the index? Does it update an existing index? If it updates the index, does it know if a file is delete? Does existing index reuse existing data or reindexs everything again?

So far, I uploaded new files to an existing blob storage and I was able to create a new version in the data source pointing to the same blob storage and I can see the new files in the explorer. But I want to update my existing index again, manually, without creating a new one.
