We operate in a SAFe development organisation and it would be great if we could create our own custom calendar resolution that shows each PI - as an alternative to the current options of Days, Week, Month, Quarters.
PIs can be set manually with start stop dates - not all PIs are equal in length due to holidays and key events in the year.
This is a go/no go for anyone that is working SAFe and using sprints and PI (product increment). without it Aha! is not usable. waiting for it to be released to start using aha.
another question is there a workaround / best practice to get such effect
This is a continuous source of confusion for us as well. We have 10 week Program Increments. I show Releases to various business stakeholders who really don't know what a PI is. For me, it would be nice to line things up, visually, to PIs given the specific start and end dates of PIs.
This would also be helpful to show sprints on the roadmap rather than looking at weeks.
