[opensuse-factory] Moving a project to a different location

Hi, not completely a Factory topic, but I trust that one of you has the right idea.... I have two projects with around 50 packages each, which I need to move to a different location on the build service. AFAIK osc offers only the option to do this package by package, but not a whole project in one run. Any idea or tweak to ease the work with osc? Bash script might otherwise be the last resort. Thanks Axel
