Tagging subtasks


We use Subtasks a lot and also Tags. When we create a task and then several subtasks within it, it is time consuming to add a Tag as you have to go into each Subtask and tag it and then come back out to the task and repeat with the next Subtask.

Subtasks already have icons within the task display for Due Date and Assignee - can the Tag icon not be added also for quickness or is there another way that I have missed?
