How to edit dashboard to use token values to determine table cell color ranges?

I've gotten a statistics table with cell column color formats changing depending on a value, such as:[#D93F3C,#FFFFFF,#FFFFFF]99,100 but I would like to provide the ability for the user to enter the cut-off value using an edit text field and token, such that the user can set the range tolerance, like:[#D93F3C,#FFFFFF,#FFFFFF]$tolerance_range_break_value$,100 but the dashboard does not appear to accept tokens at this point in the source. Is there a better way to achieve a variable range value for the format color?
