Rush Hour for Multiple windows

Hi,

Having issues with OTM Rush Hour functionality. If there are multiple rush hour windows, it is not adding them up. Below is a scenario

Created Rush Hour data for locations A to B

1. Lane A to B created
2. 2 Calendars with RUSHHOURS activity created

A. 7.00 - 7.30 AM - 10 Min Rush Hour
B. 7.30 - 8.00 AM - 15 Min Rush Hour

When planning an order that is travelling from A to B from 6.30 to 9 AM, expected the Rush Hour would be a summed up value of 25 Min. But OTM plans with Zero Rush Hour.

Even looked at the option of putting an average value for the whole hour. But OTM does not apply partial values. Meaning, if the shipment traveled only 10 min of a 1 hour Rush Hour window, it applies the complete Rush Hour delay.

Any ideas would help.

Thanks
