I do this by making two scale bars and using guide lines to snap the top of one to the bottom of the other. Then selecting both items and doing "align left" to have both left edges the same. After that group the two and you you have one object with both bars. Not a one click solution but it only takes a minute to do.
Our workaround to save a little time is to have two scale bars in our styleset, one for the rake with tics up, one for tics down. This saves some time, but it is still a pain, since we need to do this for every published map and figure!
Our standards for page size maps require a rake with English and metric units. Not so easy as Curtis pointed out, but required so it is a little more time consuming to add two scale bars for every one needed.
We are required to put both meters & feet measurements on our maps, so this would be very helpful. It is a pain to do it separately & get them to be the same!
