There’s no way to set this value per-topic, so that feature doesn’t exist @vegabomb.
As for the original query:
Contrary to this statement, editing the last post indeed bounces the topic, so the goal is achieved.
I would submit that Glen should probably start a standalone topic for his project, with the name of it in the title so it’s easier to find, etc. Then the amount of sequential self posting he can do is unlimited in his own topic. The behavior nudge is correct in this case, because that’s a better outcome for the community: topic is easier to find, topic is easier to update, topic more correctly reflects actual ownership (Glen’s project → Glen’s topic), etcetera. You could cross-reference / cross-link the “generic plastic creators” with the individual topics as well, of course. And Google would show a boost for anyone searching for Glen’s yo-yo by name rather than the generic “anyone creating a plastic yo-yo” title, etc. Best of both worlds, really!
There are two existing solutions to this supposed “problem” already on the table. I’m not sure why there need to be more?
(It’s also funny that Glen “wasted” one of his two sequential replies on a nonsense post in that topic as well … maybe … don’t do that next time? You can also delete a reply to make room for one by pressing the delete button. Just sayin’ )
