ember mirage seed db dynamically

I know when application loads, mirage seeds the database. But I wanted to know is there a way to change the seeded database dynamically later on (for example on some user actions).

So, I have an API which gives me the status of the progress and I am polling that API call. Initially Mirage seeds the database for me but every time I make that API call, same data is returned and I want the data to change so that I can test my UI design. Is there any way to do it?
