hello, i am running an experiment where i would like the group id number to determine which block to start off on (e.g., if the group ID is 15, it should start on block 15). i have previously done this using the 'skip' attribute, but here, my blocks are selected from a list and so there's no clear place to put the 'skip' attribute. code below, thank you for your help!
