Is it possible to declare a Fortran dynamic array with lower and upper bounds

For static array one can explicitly define the lower bound like this:

real, dimension(2:6) :: numbers

I understand that dynamic arrays are declared like this:

real, dimension(:), allocatable :: numbers
allocate(numbers(6))

Is it possible to declare a dynamic array with a lower bound and/or an upper bound? If yes, how? If no, is there a reason why was this not or can't be implemented?

Yes, very simply:

allocate(numbers(2:6))

The upper bound must always be specified, but the lower bound is optional (and taken to be 1 if omitted).
