Ahh, my favorite topic - sectioned text files 
Yes, it’s surely possible. I’ve designed a part of workflow that identifies sections (groups of rows) and parses them. The project is not complete (section details need to be parsed further), but you can get the idea which is:
- Identify the start line of each section, and then
- Mark the whole section with the same ID until the start line of the next section.
I’ve also slightly edited the source file (removed extra spaces) as its structure was slightly distorted probably during data anonymization (those new names, lol !).
If you need help with transforming it further, let me know.
