Why can't I see all days off taken, to date, within a sprint, for the resource?

[Kristine Williams]

Jira capacity tracker allows us to see the remaining days off a resource has, and I understand the purpose of this, but I often want to be reminded of how many total days off a resource has planned for the sprint.  This being visible would help a great deal, as I frequently review where a resource is at during the sprint and the reminder that they have fewer points/aren't at capacity because they have used time off that had been planned would paint a clearer picture immediately.  I have a large team, so remembering who planned how many days off in the sprint is difficult, unless we're managing another "time off" list somewhere else.  the current view showing us how many days off are remaining in the sprint for the resource only gives me a piece of the information I require to communicate with the team and my leaders.
