Part pricing on BOM

[StormTrooper]

I my inventree I have various parts with BOMs and have been looking at part pricing recently to see what the current actual cost of building something is.

The part pricing is derived from previous PO's and gives me a min and max price (Based on years of PO's)

How can I find out what the most recent price for a build is? Giving min and max is not helpful in my case as I want to know what it costs to build as per the last PO.

Is there a easy way to do this? Should I just delete old PO's and only keep the latest PO?

Can this be automated?
