Match the external release date to the internal one Merged

It's really useful to be able to have a separate external release date, and to roll that date up to a month or quarter.

However, I'm finding that in all of my releases, the actual date - down to the specific calendar day - for my internal and external release dates is the same. I still want to be able to roll up the external date to a month/quarter/year, but it is inconvenient to have to update both internal and external dates any time the release plan changes.

The impact now is that I could accidentally update my internal date, but forget to update the external date, which could lead to my external roadmap view getting out of whack.

Something as simple as a checkbox saying "Same as internal date" should solve this problem. Then, updating the internal date would automatically update the external date (but of course not change any month/quarter/year roll-up settings.)
