JIRA Plans: sorting via a field using custom ordering

[paul_marsh]

I am trying to sort a series of JIRA plan board in the timeline view based off the status attribute of issues on the board. The only means to sort of this field appears to be alphabetically asc or desc. 

Instead, I would like to order the board based off the logical flow of the statuses.

i.e.

Statuses could be Open, In-progress, Closed

Ideally sorted in the order above. Alphabetical instead would sort as Closed, In-Progess, Open (or the inverse).
