The Undo (Ctrl Z) Shortcut on Toggl Plan

I’m using Toggl Plan, but I noticed that I can’t undo a drag-and-drop action on the timeline.
For example, after I move a task from the 15th to the 16th, pressing Ctrl + Z doesn’t change anything (it doesn’t move the task back to the 15th).
Does this mean Toggl Plan doesn’t support undo for timeline actions?
