I am working on creating a Product timeline view by Program Increments (PI). Unfortunately PI planning dates are not exactly the same as the quarters but very much equivalent to it. Example: Below could be a Program increment time period:

PI -1   - Jan 15th to April 15th

PI-2    - April 16th to July 15th

PI 3   -  July 16th to Oct 15th

PI 4   -  Oct 16th to Jan 15th.

Currently in  lucid spark, below is the view we are able to get. Do we have an option to edit the quarters to have something like a ‘Custom’ Quarters’ ? This will help in adding ‘Custom’ dates?
