I believe broker-linked accounts require custom symbol mapping. For Interactive Brokers for example, U.S. stocks like VT are recognized without issue. However, non-U.S. stocks, such as VWRA, are not recognized correctly, making information like the "last price" unavailable. It would be beneficial if users could perform custom symbol mapping—for instance, mapping "VWRA: VANG FTSE AW USDA" to "VWRA.L."
