Different expiration times for different categories

Hi there, I just purchased your plugin as I need to be able to automatically set post expiration dates on posts within specific categories on the website. However, I need to set different expiration dates for different categories. So posts from cat-01 expire after 4 weeks and posts from cat-02 expire after 7 weeks. It's essential functionality for me as posts are automatically generated by users filling out a Gravity form and they are only allowed access to the post they create for a limited amount of time. That time depends on what category the post they created is assigned to. Is there a way I can do this with your plugin? Or a work around strategy I can consider? Best wishes Sam
