Different SLA's for different customers

We have different SLA's for different customers, special agreements and such. Would it be possible to add an override on the report page for SLA summary and SLA detail so that we could put in a different "goal". That way we could schedule a report with an SLA of 99.975 for one company while generating a report for another with an SLA of 99.90. The existing monitor SLA would serve as the default SLA.
