In an at least two level pivotgrid scenario, it would be nice to have the option of calculating the percentage of the inner level within that level and not based on the grand total (i.e. on the subtotal of the parent). In the attached image we can see that the inner levels have percentages based on the grand total instead of percentages of the category they belong. For example Diprivan should have a percentage of 100% since it is the only element of Astrazeneca. Same goes for Astrazeneca since it is the only element of Anesthetic, General.
