Completion Checkmarks For Hosted Events

While I absolutely love that we do not need to follow preset quests or missions, I personally sometimes need and love the structure of the checklists in aspirations and the guidance it gives me. I wish this could be applied to hosted events. Same feel giving us milestones, because sometimes I want a storyline where a particular sim has experienced "all of them", and a tracking completion system would help. For example: indication the sim has had a birthday party and a family reunion and a sleepover and an engagement party. This would entice me to have actual weddings more often instead of "elope now" if there was a satisfying completed mark as a reward. Even if I make the choice to have more than one I would still like to be able to see my sims experiences as having been completed. Especially with rotation play.
