Display sum of numeric field in Roadmap View

[James Conway]

The list view (e.g. Delivery Status) allows you to sum numeric fields so you can get a value per grouping. However as far as I can tell I cannot group by Project Start / Project Target.

The Timeline (e.g. Product Timeline) and Board (e.g. Product Roadmap) views allow you to see the Project Start / Target or Roadmap columns, however you do not appear to be able to show sums of numeric field per grouping / cell. It only counts number of ideas

(Mockups of what I am looking for...)

The only workaround I can see for now is to use a multi-select field for each quarter, then use a list view, but having this sum on the board / timeline view would be preferable to support our team transitioning from Productboard.

Are there any other options or approaches available?

Good afternoon - you're one step ahead of me, how did you even sum the Linked Epic Points (assuming this is a Custom Field on the Epic) in a Idea Custom Field the first place?  

My regular JIRA Cloud automation methods don't work (lookup linked Issues or join via JQL as it doesn't seem to be able to read values from within the Epic Fields in the same way unless I'm missing something very obvious!)

Asked my question here too

My epic points were a custom field on the JPD idea i'm afraid
