Precious Metals portfolio tracking

• I’d love to to be able to track the performance of my physical precious metals - gold silver and platinum
• I hold PM across all of my portfolios, but I have to manually update the spot price to track how they’re performing in each of the portfolios, so that’s a lot of duplication
• This takes a lot of time to do, because I have to specify the price per unit, and that differs as gold is counted in troy ounces and silver in kilos
I wouldn’t think it’d be that hard to integrate the real-time spot price of these metals
