I have added this for the next Toad beta. Please test it. It is a very advanced feature, so it is only visible when you CTRL+Right-Click on one or more apps or actions.
In this video, I right-click on an app and change the path for all of Export Dataset actions. You can select all of your apps to do this at once for all of them. Then repeat the process to change your script actions.
Please try it in the next beta (available Dec-11-2023) and let me know how it goes.
