Minimum font size is 5pt, but "default font size" (in Option->New Notes) can only be set to 6pt at the smallest

If I select any note, and press the shortcut for “make font size smaller”, I can shrink the font size down to 5pt.
Likewise if I open the Inspector I can set the selected note font size to 5pt.

However, in Options->New Notes, I can set “default font size” only to 6pt at the smallest.

Would it be possible to allow “default font size” to be set to 5pt?
Thank you in advance.
