Splitting, totaling, and reporting of loads by ""Shareholder

Right, it needs a loads Splits table, and the trick is to make a URL formula button to create the correct number of splits and assign them to the corect shareholder.

We would need to understand where the info is recorded as to the shareholders involved in each load. Is that done on a child table already or just a few fields on the load record done manually per load or how? That is the missing information so far in this question.
