Issue with getting a cloud HCM custom Cheque report to run using its custom template

I have created a custom Cheque report, data model and template to process employee pay checks. The problem I am having is finding a way to have the custom report point to the custom template when processing checks. It looks like I need to create a new report category and assign it, but I can't seem to find the way to do so. I have found a few articles around this but not from a specific Oracle Doc, etc. This is my first attempt working on the Cheque Report.

Would really appreciate your help!
