Select NAV radio for AP in OEM Version ?

[Matchstick]

Hi,

is there a way to select which NAV radio feeds the AP/FD when using the OEM version ?

Cheers

If there is, I have not been able to find documentation on such in the 'readily available' documentation I have.  I'm still poking around on this one for more clarification.
