Hey @hodor, first of all sorry about that new feature in OpenStudio 1.7.0, we will get to it eventually ;-)

Secondly, you shouldn't be modifying OSM files in a text editor unless you really have to. However, if you really have to, creating handles by changing a few digits is not a good idea. The handles are supposed to be Universally unique identifiers, changing a few digits is likely to end up generating conflicting handles at some point. There are several web tools that will generate good UUIDs for you. Just create a new handle for each object and you will be fine.
