Avoid recalculation of Result Datasets?

I have created a time-dependent 3d model that involves the transport of a gas species, and my interest is to identify the bounds from an outlet where this species is higher than a certain concentration. I know I can do this with a combination of a Filter to set the bounds to that concentration, then a Maximum that looks for the largest value in the direction of interest from that Filter. Then, numerically I can run an evaluation, using the Maximum transformation across the time series, to find the largest value of this dimension across the solution time. This process takes a bit of time since, based on the Progress window, it has to dynamically create the Filter dataset, then the Maximum dataset each time. For most smaller problems this isn't an issue, but for the current problem I have it takes around 5 minutes to do these. And then atop that I need to verify through multiple parameterized runs.

I know that it is likely only dynamically determining the dataset results when needed since that would updated with any change in the solver and will save memory. But assuming that I consider my solver results to be fixed and not going to change, is there any way to force COMSOL to permanently save the results of a dataset so that I don't have to have COMSOL keep regenerating those every time? I would expect that building the initial "permanent" results from the Filter and Maximum steps will still be one long time consuming step, but after that, the evaluation steps should then be quick.
