Hope you have been able to identify the configuration you need. Very happy to help.
Dataview is very good at collating data. Probably best to start a new thread with specific details of what you want to achieve and a sample of the data fields you want to track. Hopefully, someone will be able to help.
I don’t track tasks in Obsidian. Again, it is probably best to start a separate thread that other people on the forum will see and be able to respond to with their specialist knowledge. If you can give details of what you want and samples of the type of data you want to track, I am sure someone will be able to offer you help and advice.
Best.
