How to select Aim 7?

[DST]

When I have sidewinders, amrams and sparrows loaded, and I cycle with weapon select switch through weapons, I only can select amram, sidewinder or gun. How do I select Aim7's, do I have to go extra in weapons loadout menu for them?

From the manual (pg. 295):

Undesignate / Missile Reject Switch (Boat Switch)
In A/A radar or in A/A PACS page, short pressing forward (<1s) rejects the
priority missile type and chooses another active missile type.
If there are different types of AIM-120s, it would cycle through the types (AIM-120V,
then B). If there are both AIM-120s and AIM-7s, each Each BOAT FWD would go
back and forth between AIM-7 and AIM-120.
