Numbers confused with words (2 typed as to, 4 as for) can a numbers only switch be added?

[beng-tang]

I want to use nerd-dictation to type numbers into a spreadsheet. The problem I am having is that with the --numbers-as-digits switch (no numbers-min-value switch is used) certain numbers are types as words.

Most commonly, 2 is typed as "to" and 4 is typed as "for". Other possibilities in some accents might be 6 as seeks or sikhs or sex, and 1 2 as want to, 3 as free.

Is there a way to restrict it to only recognise numbers? Like a --numbers-as-digits-only switch. This would be very useful for use cases like data entry where the main input desired is numbers and not text.
