Amazon Connect now supports selection of multiple blocks within the contact flow editor

You can now select multiple blocks at the same time and rearrange them as a group within your contact flows, saving time and effort. Previously, moving a sequence of blocks would require each block to be individually dragged and dropped. This feature is replacing the repetitive task of dragging one block at a time, which was frustrating, error prone, and time consuming, replacing it with one that takes seconds.
