This is my model, I am working on building a mathematical model and would like to be able to represent the constraint like this: `I[1] I[2] I[3] I[4] I[5] I[6] <=1500`

```
using JuMP, GLPK
m = Model(with_optimizer(GLPK.Optimizer))
c=6
@variable(m,I[1:c],lower_bound=0)
Ii = transpose(I)
@constraint(m, Ii[1:c].<=1500)
```
