Currently we have the two options for the property AllowInCustomizations:

• Always
• Never

It would be useful to have an additional property to only allow adding this field to a page via a page extension in an app.

e.g. when we add a new field to the SalesHeader that is only useful for quotes then I'll add this field only to the sales quote pages.

I would like to avoid that users see that field on the new profile customization mode.

Developers should still be able to add this field to custom pages via page extensions.

Currently the the property AllowInCustomizations has influcence on Page Extensions, too.

There's an github issue for this topic: https://github.com/microsoft/AL/issues/7771
