Allow Continuous Blog Generation with Fewer Initial Keywords in Autoblog

Currently, when creating an autoblog, the system generates blog posts based on the number of keywords inputted. However, it would be helpful to have the option to input a limited number of keywords (e.g., 5) and still generate an ongoing series of blog posts. This feature would allow users to set up indefinite weekly blog generation without having to manually add more keywords over time.

It would be great if the system could automatically expand on or rotate the keywords, ensuring that content keeps getting generated for extended periods without user intervention. This would make the autoblog feature much more efficient for long-term blog strategies.
