That should still work fine.  The purpose of the "name=bar" thing is to
decouple the checksum from the exact URI in use.  So, you can write:

SRC_URI = "${MIRROR}/somedir/${PN}-${PV}.tar.gz;name=mytarball \
           ${OTHERMIRROR}/${PN}-${PV}-extra-files.tar.gz;name=extrafiles"

and then, in another file if you prefer, add:

SRC_URI[md5sum:mytarball] = "d3b07384d113edec49eaa6238ad5ff00"
SRC_URI[md5sum:extrafiles] = "c157a79031e1c40f85931829bc5fc552"
