Thanks (again). ConTeXt is always full of ressource ! I did not know we could do this, even if I realized now that there is a similar example in the wiki. 

For the list, in case in the future this would be useful for another user, below is the complete minimal example using this approach.


% ----- Minimal working example :

\setuppapersize[S5][S5]
\enablemode[Professor]

\defineblock[Complement]
\setupblock[Complement][
	before={\page[yes]\setuppagenumber[state=stop]\setupheadertexts[]\setupbackgrounds[page][background=color,backgroundcolor=red]},
	after={\page[yes]\setuppagenumber[state=start]}]

\starttext

	% Let's process the summaries  ------------;
	\beginComplement[Two]
		Last course, we have seen A.
	\endComplement

	\beginComplement[Three]
		Last course, we have seen B….
	\endComplement

	\beginComplement[Three]
		Last course, we have seen C….
	\endComplementThree

	\beginComplement[Four]
		Last course, we have seen D….
	\endComplementFour
	\beginComplement
		and E !
	\endComplementFour
	% ---- summaries: end   ------------;

	Let's begin course 1. 
	This is course 1 : a lot of pages here about A! 
	\page[yes]
	
	Let's begin course 2. 
	\doifmode{Professor} {
		\useblocks[Complement][Two]
	}

	This is course 2 : a lot of pages here about B and C! 

	\page[yes]
	Let's begin course 3. 
	\doifmode{Professor} {
		\useblocks[Complement][Three]
	}	

	This is course 3 : a lot of pages here about D... ! 
	\doifmode{Professor} {
		\useblocks[Complement][Four]
	}	

	The course 4 ! 
\stoptext

% ----- Minimal working example  : end --------
