Problem

As of now, the first sprint created on the Scrum board starts with '<project key> Sprint 1'

Suggested Solution

There should be a way to set up the sprint name while creating it instead ff editing it later.

Workaround

The workaround is to edit the Sprint name after creating it.
For example:

• Edit the existing sprint name with 'xxx/yyy/zzz-FY 2022 Q1'
• Create a new sprint, and it will be in the sequence (next consecutive number) 'xxx/yyy/zzz-FY 2022 Q2' 

Note:

If a sprint name ends with a number, the next sprint will acquire the next consecutive number.

If a sprint name doesn't have a number at the end, the next sprint will acquire (2) at the end.
