I have got the group of sales staff's figures with multiple invoiced values for each project per staff in a List.

When creating an Indicator using data in SharePoint list, is it possible to make the status icon rules computed against the indicator value ?
For example, a sales has a invoiced figure and a target figure in a list but you can not select the target figure in "Display when has met or exceeded goal" and "Display when has met or exceeded warning"

I know thet the excel data can do so but I can not SUM the figures for each staff and this loses the function - "Calculation using all list items in the view".
