orgtbl export linbread source code possible?

[Thorsten Grothe <privat@th-grothe.de>]

Dear List,

I have an org-radio table which I would like to export to latex. The
table header looks like this:

#+ORGTBL: SEND sec-6 orgtbl-to-latex :skip 3 :splice t :lend
"\\\\\\cmidrule(lr){4-4}\\\cmidrule(lr){5-5}\\\cmidrule(lr){6-6}\\\cmidrule(lr){7-7}"  :hline
"%%"

as you can see there are a lot of \cmidrules in the code which are exported to
one long latex line like this:

\cmidrule(lr){4-5}\cmidrule(lr){5-5}\cmidrule(lr){6-6}\cmidrule(lr){7-7}...

is it possible to add a linbreak after two or three \cmidrule commands so that
it looks like this

[tabular code]
\\
\cmidrule(lr){4-5}\cmidrule(lr){5-5} [linebreak]
\cmidrule(lr){6-6}\cmidrule(lr){7-7} [linebreak]

... 

Thanks in advance!
