I was able to solve my question myself. Anybody who is facing the same task check the following pastebin. mutation editPrintroll ( $ID : ID! $printrollctx: [PrintrollPrintrollctxDy - Pastebin.com
I will now fetch the data and transfer it into the variables. Now when I like to add something to a dynamic zone, I will take all data and add new data on top. Bring all together in the variables and mutate it. Bam! If I like to delete a specific one I will remove it from the fetched data and mutate it again.
Cheers everybody
