Several midifiles together

[philippe hezaine]

 Hi
version 2.8.1-4 (Fedora 4)

After reading in the list, I have built a template for put several 
midifiles in one file .mid
(see below)
Is it possible, in a similar way, ie. with the identifiers upperun, 
upperdeux ...
and then score, to make a template for the layout ? (with indent for the 
first system
of each piece, for instance)
I know an another way for make it, but, to my limited knowledge, the 
typesetting for files is different
and I must treat the issues with separate files where copy and paste 
aren't so easy.
Otherwise, I don't find good solutions for layout with this template.
Is it possible ? Any help ?  (Please, tell me if it run for you)
   Thanks
