 if, on or before December 31, 2023, I am able to create a multi choice market in which some choices can resolve before others. Otherwise, this market resolves as 

This could be useful for questions about when a specific thing could happen - for instance, I have a market asking when the next Pokemon Presents will air, and it would be convenient to be able to resolve "June 2023" to NO at the end of June 2023, "July 2023" to NO at the end of July 2023, and so on. It could also be useful for markets like "who will run for President in 2028" - choices about specific candidates could be resolved as YES upon the announcement of their campaigns while other choices remain open, for example.

Currently, this is possible on Metaculus, but not on Manifold. I am not a web developer, and I have no idea if this is possible or feasible to implement on this site. It would be cool, but I won't be upset if it can't be done.

This market resolves as YES even if the feature is later removed (for bugginess or other reasons), as long as I can create at least one market that meets the criteria at some point in 2023.

I will not bet on this market, aside from an initial 20 mana on NO as insurance, which I will not sell prior to the market resolving.
