Is there a way to automatically create an array of subscripted variables given `n` in `Symbolics`?

For the case `n=6`, I would like to do what the code below does without having to type out the variables explicitly.

```julia
using Polynomials, Symbolics

@variables a₂ a₃ a₄ a₅ a₆
a = [0, 0, a₂, a₃, a₄, a₅, a₆]
p = Polynomial(a)

```

From the `Symbolics` docs, it is possible to do something like

```julia
@variables a[1:3]

```

but then I cannot start the array from index 0 or from another arbitrary value, which is what I want so that the index of the array matches the exponent of the monomial. I have managed to do this with `Sympy`, but would like to have the same kind of array with `Symbolics`.

Open an issue. This is more of a feature request. We used to have a simple way to do this and it would probably be good to expose it again.

Thanks, I made a request at [It would be interesting to be able to create an array of subscripted symbolic variables automatically · Issue #694 · JuliaSymbolics/Symbolics.jl · GitHub](https://github.com/JuliaSymbolics/Symbolics.jl/issues/694)
