Is there a way to change the Source so that it matches the Input name instead of the Storage Table name?

I am collecting data from an Azure Storage Account, and I have several inputs that use tables with the same name (e.g. AppMessageLogs). Splunk uses the table name to populate the source, so the problem is that I have no way of knowing which input the data is coming from. A different add-on for MS Azure used the Input name as the source.
