Creating a 4D array.

I have a 3D array, P_3D, which has the dimensions 1x301x1000. I want to make this a four dimensional array by 'inserting' another array consisting of values for time into P_3D, the time array, t_n, has the same dimensions as P_3D.

Is this possible?

I can give some background on the problem as a whole if that helps.

Thanks
