Percent based comp rate code...round to 2 decimals in COMPENSATION/JOB?

We have a request to be able to set up percent-based comp rate codes, but then round them to 2 decimals and not 6 (as delivered). I found the rounding rules table for eComp, but we don't own/can't use it. Does anyone know of anything else delivered we might be able to utilize?

I am considering a custom SQR that would go in and calculate these comp rate codes to 2 decimal and sql update the values as needed. Not ideal, but not finding any other options as of yet and I don't want to have to calculate the percents and set up 39 different rate code defaulting rules and maintain that annually or keep our extra salary grades and steps (which is what we have now and are trying to get away from).
