How to got the ILS FREQ/HDG to be entered automatically on the NAV/RAD page of the CDU:

1) Load the route - RTE (RTE 1) > SEND > FLTSIM FPLS > KBOSKPVD06
2) ACTIVATE > EXEC
3) DEP/ARR > KPVD ARR > ILS05
4) EXEC

Once I did that, when I checked the NAV/RAD page, I saw:

ILS MLS
109.30/048PARK

NOTE. After selecting ILS05, and after pressing EXEC, I had to fix the Route Discontinuance. I select the waypoint KENTE (directly below the Route Discontinuance) and pasted it over the KENTE waypoint that had loaded with the route, then press EXEC again. The ILS FREQ/HDG remained 109.30/048PARK, so I was good to go.
