Trivial (?) question re dynamics positioning

[Thomas Ruedas]

Hi,
lately I have been wondering about how to position dynamics commands 
(i.e. f, p, mf, etc.) so that they are exactly in the middle between 
the two staves of a piano score. The way suggested in the docs is to 
put them into the notes of either the right or left hand, but this 
results in them being closer to the upper or lower staff, 
respectively, and makes it look as if they would only affect the 
corresponding hand, which is not normally what I want.
The insertion of the dynamics in the part of one hand or another also 
has the side effect that in the MIDI produced from it, only the 
respective hand is affected by the dynamics command, but not both, 
with is (usually) not what I want either.
Any solutions?
Thomas
