Custom fields in msdyn_projecttask - part II

Hi,

Via make.powerapp.com we've added a custom field to the msdyn_projecttask table (Tables -> Project Task) 

(see image below)

We can successfully read and write this data via the Power Apps REST API, which is great. 

However - does anyone know if there's a way to get this custom field to show on the Task Details forms at project.microsoft.com ?

(image of the form I'm asking about below)

Many thanks
