From some other forum discussion I learned that I can programmatically add names to the different “blocks” of a multi-block dataset. These names appear nicely in the “Multi Block Manager” which is very helpful for the users in the case of very large MB Datasets!
However, I did not find so far any way that the user himself can directly manipulate these names: Is this even possible, and if yes - how?

There is no way to specify block names in ParaView GUI (except through programmable filters ofc).
I had a small prototype for adding a name param in the group datasets filter but never merged it.

ParaView now contains a GroupDataSet filters that support renaming blocks.
