You can achieve that already by chaining features together - using a Servant and Keyboard Shortcuts.
i.e.
- You can use Shortcuts to 'select a One Click grid layout' and 'Select a Custom column profile' and assign both to the same shortcut.
- Then you'd create a Servant that uses the 'Display a Market on a Trading screen' rule type and on the parameters page configure it to 'Trigger a Keyboard Shortcut on the displayed screen' (using the shortcut that you previously defined).
- Finally via the API you use displayMarket and then startAutomationServant to trigger the servant that will run your keyboard shortcut
