Is possible to create parent / child relationships between cases from Robotic Studio?

We have 2 automations- creating case 1 kicks off automation 1, which creates cases that then kick off automation 2. We're wondering if there is a way to essentially say, "don't mark case 1 as completed until all of the child cases have finished processing". We need to be able to tell when a certain request that might have multiple work/queue items is done processing, so that we can do some post-processing work such as zipping all the files up into a singular folder, closing the applications/websites the child cases were using, etc. etc. Is this possible?
