That sounds good too.
How would I go about implementing this?

Can this be done from a single ctest job script run or would I have to 
run it once for each buildid?

I assume it would involve more than e.g.:

set(CTEST_BUILD_NAME "${CTEST_BUILD_NAME}-emma")
ctest_submit(CDASH_UPLOAD ... CDASH_UPLOAD_TYPE JavaJSONTar) ?

I was thinking separate summaries like I would get from distinct builds.

If I can submit just the emma coverage under a new buildid that would 
basically be what I want.
