How do I get target begin and end (portfolio) to auto populate when I add a story to a sprint?

[David Prather]

I would like to be able to put a story into a sprint and have the begin and end dates of the sprint auto copied to target begin and end dates of the story - such that in portfolio the story will be seen on the roadmap and the epic that it has as parent should reflect those dates as well.

Is there any way to make this happen? Otherwise I will have to manually change target begin and end if the story moves to another sprint. And this will then be a source for error.

Thanks in advance!
