Hi John,
This is not something we are considering on the Planning Analytics roadmap. At least not in the form of extensions to the capabilities of TI processes. Our intent is to make TM1 Server more accessible to ETL tools. This means new ODATA API endpoints in the TM1 Server that make it simple for ETL tools to load and extract data from cubes.
I would love to see some sort of tool that could extract data from Cognos and load data into TM1. I'll ask the Cognos team if they have a modern way to extract data from data sources or packages/data sets in Cognos.
