There’s an open pull request that sounds like it implements something like this. If you have access to the Unreal Engine repository you can take a look at it here: Add support to spawn actors in the middle of a frame’s timestamp
If you’re willing to use a customized engine then you can integrate these changes into your own build. But keep in mind you’ll have to maintain these changes as well whenever you update engine versions. Depending on the number and scope of the changes and how many people work on your project this can take a significant amount of time that you don’t have to work on the game itself.
