A long time ago I needed something like that so I ditched footnotes and put it in as text in the body and tinkered till it was just right. Later someone tried to re-create the same thing but lost a few weeks (until they asked me how I did it in that document.)

Word is not strong at type setting so workarounds are very common. Another old trick I used involved sending the paper through the printer 2 times. The next person that tried to recreate that document lost a month (until they asked.)
