Abilit to split a single topic into multiple topics

Users sometimes include multiple requests or ideas inside a single topic. It would be great to be able to split a single topic into multiple topics such that each resulting topic appears as submitted by the original topic submitter. We could then edit the resulting topics down to contain only one idea each.

Here's the workflow we imagine:

1. User submits a topic that includes requests #1, #2, and #3.

2. Agent splits the topic into three separate topics.

3. Agent edits one of the topics to include only #1, the next one to include only #2, and the last one to include only #3.

I suppose in this sense, split=duplicate.
