The server does support what you propose, in a limited way.  If I 
specify the tournament format as "Round Robin", and the number of rounds 
as "2", it operates a double round robin, in which each pair of 
opponents plays twice, though not consecutively.  And after the changes 
currently being tested, the colours will alternate.
