Can product architects (PAU) define an "phantom" part in web app Product structure editor?

Dear DS and partners,

two weeks ago I asked a similar question how to define phantom parts within XEN and Engineering Release and it works with native client B.I. Essentials.

Now I want to know if there is a possibility to define such phantom parts (like skeleton) with the PAU role in web app "Product structure editor". The attributes "V_inEBOMUser" I've activated and a filter can be created in it. An edition of this attribute is not supported yet and can be canged only in native client. This way of working is a little bit boring.

Is there any other user friendly way to set a 3DPart or Physical Product as "Not instantiated in EBOM" from web app? Or can it be developed?

I'm using 2021x oC.
