Thanks for your posting. We currently don’t have an ETA for the bulk-edit feature unfortunately. It’s one of the next bigger features we would like to work on but it probably won’t be available within the next few months unfortunately. That said, it’s high on our todo list as this is a very popular feature request. There are a few workarounds for this in the meantime as mentioned in the other postings (i.e. XML import + update option or using the API).
I hope this helps and please let me know in case you have any further questions!
