Hi Laszlo,
You may want to explorer the test REST APIS that BAW offers, for instance:
https://www.ibm.com/docs/en/baw/23.x?topic=ti-get
help you retrieve information about the task, including its data.
Using these APIs give you more options if you want to build your own Dashboard.
One more thing to explore would be the use of external Database to hold the content of the list, which can potentially reduce the size of the BPM tables. It may also be a good idea if you are planning to have reporting capabilities of the items in the list.
Regards,
Ivan Martinez
