This is basically a duplicate entry of this questions from 2014, but 3 years have passed and I thought I give it another try:
For sprint planning, it is crucial to get the total estimated time in order to compare it to the time available in the sprint. As far as I can see, YouTrack only gives you that number for tickets that already have some Spend Time value. Even if I set the default value of Spend Time to 0, the simple sum of the estimated time is not calculated. Why? Can I see it anywhere else? Its such a simple task to sum up all the estimated times, isn't it? Is this a feature you plan to add in the near future?
*Edit*: To make this clear: We need at least a possibility to globally add a default value to the "Time Tracking" sub menu. If we could add something like "Create ticket -> 1m -> Documentation" to the "Time Tracking" sub menu, the number would be computed, but I can't find any option to add default values to that sub menu.
