Add LET and LAMBDA functions for declaring variables and reusable inline functions, like Google Sheets. This adds capabilities like: Defining temporary variables inline to break down complex calculations Creating reusable function definitions to avoid repetitive formulas Writing cleaner logic with familiar spreadsheet syntax Implementation can follow Google Sheets: LET(name1, value1, [repeatable…], calculation) for variables LAMBDA(input1, parameter1, [repeatable…], formula) for functions This reduces complexity and operations in multi-step automations that otherwise need multiple individual modules.
