[GNC] Asset price source: select by account or commodity?

[Chris Skudder]

   Hi - I'm using GnuCash for personal finances.
   There are 2 distinct types of commodity assets I want to account for:
   #1. Conventional financial market securities like stocks and mutual
   funds.
   These work well using the well-established Buy + Sell transactions,
   lots, and setting Price Source as "Last up thru Report date" when
   creating Balance Sheet reports.
   #2. Home heating fuel, specifically propane gas (LPG): We buy propane
   in deliveries of hundreds of gallons. A delivery is enough to heat the
   house for several months.
   I want to be able to report the value of the propane in our tank as an
   asset, valued at the price we paid for it based on FIFO. A balance
   sheet does this when buy's, sell's, and lots are set up correctly, and
   I set (Options > Commodities > Price Source) to "Average cost of
   purchased weighted by volume."
   Is there any way to differentiate Price Source by asset? That is, set
   or select Price Source to:
        "Average Cost" for Propane, and
        "Last up thru Report date" for financial assets?
   Thanks in advance.
