It would be nice to be able to tap an already created email blast to reuse or modify. If I need to send it to a few more people, I don't have to recreate it. Or if I can use as a starting place to create a new one.
I realize the metrics are built into the blast function, so perhaps you could be able to resave it as new?
You can absolutely use an existing or past email blast as a starting point for a new send using NationBuilder's "cloning" feature.

On the Dashboard of any email blast, click "Clone" to create a new blast identical to the current one. From there you can make any changes or adjustments you'd like — or resend the blast exactly as it was before (which can be very useful for A/B testing substantially similar blasts to different recipient list, for example).
