In cases where a market has been manipulated or admins otherwise wish to hit pause on a market during an investigation/inquiry, rather than halting trading after the fact, or forcing the whole market to unwind via a Resolution NA, will Manifold developers or admins be able to roll back the market to a specific date and time prior to the alleged manipulation. The roll back would act like a partial NA, preserving trades before the identified time and undoing all trades after the identified time.
This could allow a YES or NO resolution to be carried out retroactive to the time when a manipulation occured.
Update: Mira commented:
I would like to "resolve as of a certain time" just in the ordinary course of a market. For example, news breaks, a bunch of people pile on for free money - you could only pay out the actual predictors.
If something along the lines of a resolve as of a certain [retroactive] time were to be deployed to all market creators, it would also satisfy my definition of a roll back tool available to admins and this market would Resolve YES. My mention of admins is not exclusive of availability to other users, i assume that it might be less likely for other uses to have this tool than for admins, however this could be less work for admins and a net positivefor the community. I welcome discussion of the risk benefit ratio making such a tool for everyone, vs only some, in balancing the ability for the community to self police and the potential for abuse of such a tool.

The old Free Response markets could've stuck around with a feature like this, and might be better than the fixed payout in many ways. Simply undo the pot-stealing trades after the answer is known.
@Mira incorporated the suggestion for broader availabilityinto the market description.
