Editor Script to add element to an enum

Does anyone know a way that you can modify the values stored inside an enum at using an editor script.

I am importing a list from a spreadsheet where each element has a unique Id that i would like to store on the object as a enum (this is mainly for easy comparison with later behaviours). I have got the importer working however currently i have to go into the script every time i add a new element to the spreadsheet and add the ID to the enum list. Im wondering if anyone knows of a way i can make this automatically add a value when i run the importer editor class

eg.

Enum IDS
Element1
Element2
Element 3

when i click import for a spreed sheet that i now added element4 it will add it to the bottom.

This only need to work for development so can fully be an editor class

Thanks

This can not be done as enums are set of constant values with a set size which is determined at design time.
Your best bet would most likely to be to either use a list or a dictionary.

Thats cool

I did not think it was possible with my initial research but nice to confirm. Ill work using a dictionary or something similar for the importer.

Thanks for the help
