I have a very specific use case and maybe can help me to achieve what I want to do, if it can be done at all. Basically the question is if the row number can be addressed in a formula. But I will explain in more detail for better understanding.
Let’s assume I have two tables, one is called ‘Scenes’ and the other one is called ‘Shots’. For demonstration purposes both are super simple. ‘Scenes’ looks like this:
Shots looks like this:
![Scenes|690x370]
Now it would be perfect if I could use the row numbering of the ‘Scenes’ table and create automated shot numbers within the ‘Shots’ table, that automatically adapt to the hierarchy (row number) when I shift shots and scenes around. Autonumbers don’t work because the numbers are created depending on creation of the record and don’t change when re-arranged within the table (moved up or down). Also within grouped records in the Shot’s table, all the information I’d need is already there, it’s the number in the first column (row number) but I don’t know how to access it via formula without manually entering it and changing it every time I change the order of my Scenes and Shots.
I know there are very complicated solutions to do something similar with a lot of extra cells and formulas but even then none of them works without constantly manually adapting at least on parameter when records get moved up and down. I hope it’s somewhat clear what I want to achieve!? 
I’m not sure it can be done and if it can’t if it is worth considering to add this functionality as it might be a very specific use case!? It seems to be such a simple thing if I could just use the row number that is already there and updated anyways.
However, thanks it advance for any pointers in the right direction.
On a side note: I also figured out that it is currently not possible to sort by a linked field which is maybe a separate topic in ‘Feature Requests’
