Should I use wizards steps if the user won’t finish all the steps at the same day?

I'm currently designing a system and there is this specific functionality that the user has to complete a series of steps, but the last step won't be completed at the same day (it has a specific day to be completed). These previous steps are more like preparation for the last step itself.

Is it okay to use a linear wizard and let the user complete the last step later by saving its state or should I make this last step as a standalone page?
