Splitting between two subjects in the same day

[Juan]

Hello,
I need to know how to make splittings between two subjects.
I mean a same group in the subjects of physics and technology split. One half Technology in the Laboratory and the other half in Technology.
In the end, these subjects of two hours become three hours 1h + 1D+1D.
Thanks.

Hello,

I am not sure I get what means "1h" and "1D".

Maybe divide group "physics-technology" by 2 categories, in the first category there are 2 divisions: "physics" and "technology", and in the second category also 2 divisions: "Laboratory" and "Technology". Then use groups "physics", "technology", "Laboratory", and "Technology", and maybe also the resulted subgroups.
