Adding more decimal point for XAU currency

In Indonesia, e-commerce here collaborates with Fintech startup that selling Gold in smaller amount (one can buy 0.1 gram of gold). Since moneypro support XAU currency which basically 1 xau = 1 ounce of gold, i can convert it manually from gram to ounce.However, moneypro only support 2 decimal in xau currency (e.g 0.01 XAU). I would like to request adding more decimal point in XAU currency for more accurate conversion from gram to ounce. Perhaps 5 decimal points would be awesome.
