Centered movement names

[Paul Scott]

|2.11.27 or so.

scoreTitleMarkup |(10.2.2 Custom titles) sounds like a great idea but 
not as it seems to be implemented.  Movement names are normally 
different for different movements so putting it in the paper block 
doesn't seem to make sense.

Is there a current way to change something like the current instrument 
header field for each movement?

TIA,

Paul Scott
