Conditional Bar Chart Colours

Worked on a example in https://dune.com/shogun/gmx-analytics-arbitrum for the $GMX Price Chart. It works similar to how Tradingview charts are displayed, the volume bar changes in colour based on the price change from the previous day. On Dune the work around is to have 2 separate bar columns and to display both, but this means we can see both volumes in the Tooltip. Could we get the ability to conditionally change the bar chart's colour based on a value? Thanks
