How Map From A Method Like Update ?

[AmBplus]

"I’m working with a complex model. When I need to update an instance of this model, I want to avoid changing certain fields like createDate. Currently, I can't achieve this by using a constructor with global settings to use the constructor. However, I’d like to specify a custom method for mapping instead of relying solely on the constructor. How can I achieve this using Mapster?

For example, I’d like to do something like:

TypeAdapterConfig.GlobalSettings.Default.MapToConstructor(true).UseMethod("Update");
i mean do it automate
Where the method Update would handle the mapping. Is there a way to achieve this with Mapster?"
