Welcome to the Make community!
I’ve created a new module for you to perform splitting an array (of anything including collections) into multiple sub-arrays/bundles.
Get it here: [Free App] My Toolbox of Useful Modules
Hope this helps! Let me know if there are any further questions or issues. P.S.: investing some effort into the tutorials in the Make Academy will save you lots of time and frustration using Make!
