There are some customisation options available for hierarchical funnels to make them more bespoke.
Colour Selection
Firstly the base colour can be changed by clicking on its colour - this will open up the colour picker.
There is also the option to highlight a block. This will give the selected metric block a grey colour.
To do this click on the plus button on the desired metric - this will open up more options. Then under 'Block Type' click the 'Highlight' option.
Unit Formatting
The "Full" option will display the entire number with commas to separate the thousands. The "Formatted" option will round the metric value to the nearest base unit selected.
