Yes, there is such a command.

Oh, you want me to mention the name?

reform()

You may need to use transpose once or twice to get the elements in the
order you need.

Maarten

Example:
a = intarr(2,3)
for i = 0,1 do a[i,*] = i
b = intarr(2,3,5)
for i = 0,4 do b[*,*,i] = a
c = transpose(reform(transpose(b), 5, 2*3))

or

c = reform(b, 6, 5)
