Serializing Property for Packaging

I have a custom data asset that has a bunch of UPROPERTY’s that I would like to serialize. This data asset will belong to another component inside the game map.

My custom data asset has an constructor that looks at some files and then preprocesses some data in order to fill in the UPROPERTY’s for some default values. I would like these default values to be available after packaging because currently the way that it is being packaged requires functions that are not available when not using the editor.

How do I have my custom data asset serialize the properties that i need for packaging once the initial values have already been set using the editor build?
