Granular breakdown of bunker stems being consumed in Voyage Performance Report: bunker report

We want to see the price and location of where a bunker stem was purchased in the Voyage Performance Report: bunker report. We can then accurately see which stem is used and when, so that the real price can be worked out.

Please help us with a solution that is better than our workaround - which is to manually calculate by looking at the current report details. Eg, what we do is to check the bunkers ROB from noon reports and take into account FIFO, meaning that where we have bunkers ROB, the quantity supplied in the last stem will be burned first, and when depleted we take the next stem, and so on.

The data are all there already, but not telling us what we want to know at a glance.

Maybe something like we have for Bunkers received, but for consumed (as per image).
