Hi,

I would like to suggest a function for the Whiteboard.

Let’s take the management of a object sales store for the example. I want to plan the replacement of a specific product by 2 new products. To not loose the money of the object I want to replace, I’m going to sell my stock to 3 concurrent stores.

On Whiteboard, I want to design the exit plan using **“Function Boxes”**. A function box is a box that permit to do different operations like addition, subtraction, splits, etc…

My Exit plan for the object I replace :

Then my Entry plan for the 2 new objects :

So basically, I would like to have boxes capable to do operations with the entity fields. It can be mathematical operations, string operations, etc… The boxes adapt the result based on the inputs/outputs.

In a more advanced configuration, if my Split manual box have more than 1 input, I should be able to select the entity to use on the output :

Function boxes can also integrate the Formula engine of Fibery.
