It is not recommended to use studio fields in custom module. Better way is to have the field added in python custom code with proper dependencies. 

Hello Werd,

Changes of studio are limited for the particular database. So, in case you lost your database then you have to redefine this changes. That's why it isn't recommended to use studio for longer time. And if you already created fields using studio then you instead of removing then you should redefine those fields in your custom module.
