increasing number of frequency digits in AC analysis in spice 2G6

I'm trying to increase the number of digits in the _frequency column_
of an ac-analysis like this:
..options numdgt=7
unfortunately this does only increase the number of digits in the
"voltage (and current) columns" , the frequency column however is
unaffected.

e.g.
1.122E-02 -2.153112E-02

in which the first value represents the frequency and the second a
voltage
Can anyone tell me how to make spice 2g6 to generate more digits for
the first value?

In the .AC analysis specify finer steps.

I tried this but it doesn't help as Spice just begins to repeat
frequency values in stead of refining them e.g.
1.006E+01 -3.601257E+01
1.006E+01 -3.601690E+01
1.007E+01 -3.602124E+01
1.007E+01 -3.602557E+01
1.008E+01 -3.602991E+01
1.008E+01 -3.603424E+01
1.009E+01 -3.603856E+01
1.009E+01 -3.604289E+01

Maybe it's 2G6. In PSpice, with 101 Points per Decade, I'm getting
*15* place accuracy for Frequency.

yes, it is 2G6 I am using, it seems hard to believe it is not
possible to increase the number of digits in the frequency column. Is
this a bug? Or is there a workaround (except using PSpice of course)

b.t.w. Spice 3F _does_ give 7 digits for the frequency
