Preventing panel reload for fixed relative time when time picker changes

I’m trying to prevent panels of a fixed timespan e.g. relative time of “now-7d” from reloading when the time picker dates have changed. Since “now” is always changing perhaps it’s possible to have “today-7d” since I don’t really care about what’s happened since the start of the day or a “reload only on query duration change” option? I’m trying to prevent these queries from running when the query time range hasn’t changed which slows down the refresh of the panel(s) I want updated when the time is changed. If the refresh is set to a day I’d still want the pane to periodically refresh so seems like a “today” or “thishour” so there’s a fixed start time might help to detect when to refresh.

I’m currently testing on version 8.3.4.
