How to insert two RPH values at once?

Hello, fellows.

Does anybody know how to force SBC to insert RPH with two values at once? I have configured rph-policy with inser-r-value=(wps.2 ets.0), but SBC inserts only first value.

rph-policy

       name                                   ch1to0

       override-r-value                       ets.1

       insert-r-value                         wps.2

                                                ets.0

Thanks and regards,

Daureen
