Steemit Request: Submit Story Using an Existing Post as a Template

Apologies in advance if this has already been addressed or requested, but it would be great if we could select an existing post as the template in submitting a new story.

A typical use case would be for a post that is part of a series of posts on the same subject.

This was a public service announcement brought to you by the Hive account@steemit committee to stamp out monotonous copy-n-paste. ;-)

Thanks!
