override-auto-beam-setting in \layout{} ?

[Graham Percival]

Can I specify something like
#(override-auto-beam-setting '(end * * 5 8) 3 8)

in a \layout{ \context { \Score foo }}} ?

I'd like to specify a number of irregular beaming settings in a file
which can be \include'd in many other files.  I know how to do that
with regular \set and \override commands, but #(override-auto...)
seems to behave a bit differently.

Cheers,
