Hello, I working with this equation

```
param: pol: area :=
1 4
2 4
s.t. em1{k in pol, l in pol: k !=l }: A[k,l]+B[k,l]<=0;
```

In this case the equations genered are like this

```
A[1,2]+B[1,2]<=0;
A[2,1]+B[2,1]<=0;
```

In this case the second equation it´s no necessary, how I can write it and not generate the second equation?

thank you
