Display Function AND Sub-function in Component?

Given is a function, which consists of several sub-functions. These sub-functions are realized by multiple components.

What I want to achieve is that the function 1 of the component C1 is displayed and at the same time the sub-functions Sub-F. 1 and Sub-F. 2 of the respective sub-components are displayed. (see screenshot 1).

As far as I am aware, however, I can only display either component 01 with function 01 (screenshot 2) OR component 01 with the two sub-components and their functions. Is there a special reason for this in ARCADIA or is there a workaround?

This would be what I’d like to achieve:

This is the version with the main function only:

This is the version with the sub-functions (but I can’t display the main function)
