Hi @waviles
It’s always helpful to mention the use-case. For instance, there’s a feature request (see ideas) to create an ‘academic year’ period and the use-case explains why this is needed in the EMIS implementations (Log in with Atlassian account). Additionally, here’s the community post and how that issue was handled (see the post marked as the solution): Academic Year Filter in Standard Report
There isn’t currently an out-of-the-box way to create the custom periods as you described. But it will be quite helpful if you could share more about the use-case?
Meanwhile, I will triage this to the team and ask if we could create a ‘feature request’ (idea). Thanks!
