Batch Switching Supplier

This new feature intends to alleviate micromanagement by allowing you to order your firms to batch switching suppliers in the following way:

“All purchasing units in all of my retail/factories/warehouses/all (selectable) that are buying from source X must change to buying from source Y”

For example, you may use this feature to redirect all your retail stores currently buying a certain product from a specified factory to another factory or warehouse.

Example 
Let’s say that you want to redirect all your retail stores currently buying Cold Pills from source X to Headache Pill from source Y.

Step 1
Go to a purchasing unit in any of your retail stores currently buying Cold Pills and click [Link]. (Please see below screenshot)

Step 2
Select Headache Pills and click [Batch], for batch switching supplier.
 
Step 3
The game automatically opens the Firm Report. You can use the City and Firm Type filter controls at the top of the screen to modify the current firm list. Then click [Batch Switching Supplier] at the bottom of the screen to apply the change to all firms in the list.
Step 4
Now go back to one of your retail stores by clicking [Go] on the Firm Report. You will see that your Purchasing Unit is now buying Headache Pill from the new supplier.
Step 5
Since you still have some old stock of Cold Pills at your Sale Unit, if you want to put the Headache Pill on the retail shelf immediately, you may click [Clear Stock] on the Sale Unit to discard the remaining stock of Cold Pills.
