Tag total time in json export meta data

I saw that hovering over the tag we can see the total animation time. That’s great, but I think that the place is most useful is in the metadata since reading from it in game could improve the workflow. For instance, if we have a tag representing a shoot,or a blade hit, etc…it would be very useful to be able to retrieve the tag duration to set the sound duration when coding the game.
I am sure it could be useful in other contexts too.
