I am trying to customize a visualization template.
The specific context is the FB_HeatingControl visualization

It appears that there is a visualization consisting of elements
encapsulated into a frame - (no modifications can be made here)
and if one digs further down into the common toolbox/visualization
one finds a visualization consisting of the separate elements within
the frame which cam be customized and made more compact.

However, it is unclear how to reassemble those elements into a frame

Any ideas ?

Apparently one cannot include more than one image per post in here:

Somehow the individual elements need to be gathered into a frame

You might share the whole library with us, otherwise it's impossible to help.
