Scheduling multiple events for a single post

Hello,

I stumbled upon this plugin and found it being a great solution to something I need right now. I created a Custom Post Type having a Custom Taxonomy, where the taxonomy describes a priority. There are 3 categories (A, B, C) and the frontpage orders the posts by that taxonomy, then by date.

I’m using (the lastest version of) Post Expirator to change that priority category after x days, but am now facing an issue where I have to schedule multiple priority changes, meaning:

1) Post is created and gets the priority A
2) After 20 days, the priority of this post should be changed to priority B
3) After another 10 days, the priority of this post should be changed to priority C where it either stays or is deleted after another x days

Is there any possible way to achieve this using this specific plugin? I hope I just missed a functionality, that would be absolutely fantastic.

Thank you in advance and best regards.
