How do you cache Chaos Cloth sim without an animation blueprint?

I’m new to the Chaos workflow, and I’m currently trying to get a simple piece of cloth to float onto a beam, using a wind direction blowing it, and cache it for use in a cinematic in Sequencer. I followed this great step-by-step tutorial:

However, this tutorial is for caching clothing movement while attached to a character that has animation. The problem I’m running into is that the length of the animation in this tutorial directly correlates to how long UE will cache the cloth’s movement. In my case, there is no animation; just basically watching a physics simulation happening.

I don’t want or need the first 5 seconds of the simulation (don’t need to see the cloth floating into place, just need it being blown by the wind once it’s already on the beam), so I was going to cache about 15 seconds of the simulation so I can use the last 10 seconds of it. But even if I let the simulation run and record in the cache manager for 15-25 seconds, once I stop, it only saves just over 6 seconds. Every time. I don’t see any control for setting an end point, so I’m at a loss as to what to do.

Can I actually do this without an animation driving the length of the cache? Any help is appreciated. There doesn’t seem to be a lot of documentation about how to cache cloth that isn’t attached to a character.
