[Feature] Add possibility to add additional custom obects from Typed-tab

[sepetuks]

Problem description

Better usability for user experience

Proposed solution

Be able to link custom objects (from objects type) using Typed-Tab on specific app model.

Alternatives considered

Yes using natively from Custom Objects menu is possible

Additional context

I have custom object type that allows multiobject linking of Custom Object type Objects.

It would be very nice to be able to link additional ones (Product names) from appmodel side (in this case from VM or Device view)

Not only editing it via Custom Objects menu:
