In .net framework you can use AssemblyBinding probing in app.exe.config and use Post Build Events Command Line in Visual Studio to move your dll and xml in the custom folder.
In .net core 3.1 additionalProbingPaths seems doesn't work fine but you can still use Post Build Events Command Line to move your xml in the custom folder.
Note:
1. AssemblyBinding probing and additionalProbingPaths will affect your assembly load dll location.
2. If you don't know Post Build Events Command Line see the guide line.
See the below issues about probing path.
Additional probing paths for .NET Core 3 migration
donet/sdk issue.
Finally I found nulastudio.NetCoreBeauty library which seems like you want feature.
