Hi,
In general I think that this could be a good idea.
For our journals who have asked a similar feature I have suggested the following:
- Create a new journal section and name it after the CFP theme you have
- When sending the articles, the authors can choose the correct section (CFP theme) and you can also assign these papers automatically to certain editors if needed
- When the CFP is over, you can move the articles to the correct sections they belong to and remove the CFP theme section
