Wix Functions Request: Creating Custom Variables in the Function Builder

Working on it
Currently in Wix Functions, it is not possible to create custom variables in the function builder.
Custom variables are placeholders for information you use often. You set up a variable once (like 'Maxitemweight' = 60) and can reuse it throughout your function. If you need to change the variable, you only update it in one spot, and it automatically updates everywhere else in the function.
We are always working to update and improve our products, and your feedback is greatly appreciated.
