Employer Match With Partial Matching on Service Step Table

We have a service step table configuration that allows for 100% match on up to 3% of employee contributions. After that, 50% match from 3-4% employee contribution and 4-5% contribution for a total of 3% + 0.5% + 0.5% = 4% total match on 5% employee contribution. When an employee contributes simultaneously to both before-tax and after-tax, is there a way to respect this service step setup in aggregate so that the system is still matching on only up to 5% employee contribution in total?
