How to multi-select elements in nested links (link attachments) ?

Dears,

hope you have a good day ,

I have a Revit model with nested links. Link A contains Link B, C, D... as attachment.

Main model → Link A → Link B, C, D.... (attachment)→elements I need to select

I tried

Selection.PickObjects with ObjectType.LinkedElement

works fine for elements directly in Link A, but fails to multi-select elements from Link B, C, D.... (the nested attachment).

Single selection with Pick Object works for nested link elements, but multi-selection doesn't.

Code:

IList<Reference> refs = uidoc.Selection.PickObjects(ObjectType.LinkedElement, "Select elements");

Question: Is there a way to enable multi-selection for elements in nested/attached links?
