You know? this is kinda funny, but no... If there's a "Runtime" already there, the new unzipped bundle sits in "Runtime 1", the next unzip will park in "Runtime 2", etc... It's the one funky thing ab't Macs that gets me, in that they kept the old MacOS 'replace' behavior and not 'merge' by default. OTOH, not sure if .sit files exhibit that same behavior (Macs can use .sit and .zip and .rsr and .tar.gz and...) /P
