horizontal position of augmentation dots

[Richard Shann]

I struck me that this score:

8><8><8><8><8><8><8><8><8><8><8><8><8><8><
\version "2.20.0"
A = {f2~  f8. s16 s4 }
B = {bes,2~  bes,8. bes,32 a, bes,16 c d e }

\score {
\new Staff  << 
 \new Voice   {\voiceOne \clef bass \A }
 \new Voice  {\voiceTwo \B }
            >> 
       }
8><8><8><8><8><8><8><8><8><8><8><8><8><8><

has the lower dotted note vertically aligned with the upper one (see
attached pdf). I thought it might be nicer to move the lower dot closer
to its notehead, but I couldn't find out how to do that. With a lot of
things there are properties to tweak but this didn't seem to the the
case for augmentation dots.
Perhaps someone could steer me in the right direction?
