[TenTec] Omni vii filter feq bandpass set?

[Denton]

I like to use psk with my Omni 7, but I notice that when I switch in the 500 
or the 200 hrz filter they default at about 700 to 1000 hrz in the passband. 
I typically like to lock onto a psk signal at about 1500 hrz, with pbt set 
at +400 hrz.
Is there any way to get the 1.8, 500 and 200 hrz filters to default to about 
1500 hrz?
I have both ceramic filters installed with auto selection.
Thanks in advance de Denton, WB7TDG
