Sales tax chart

To set up the formulas for this graph, you can only use the revenue group: 31101 - OPERATIONAL GROSS SALES REVENUE, but there are cases where you need to separate it out, such as when the company has revenue from services and revenue from the sale of goods. In the way the graph is generated, it is only possible to generate one of the total of sales of services and goods, without the possibility of separating them.
If possible, we would like to be able to change this account 31101 to other revenue accounts, such as 31102, 31103, 31104, etc.
Thank you in advance.
