Padding Array With Many Elements

I have 2 structures:

typedef struct
{
  int a;
} S1;

typedef struct
{
  S1[0xff];
} S2;

Let's say I only require the element 0xf0 out of S2->S1, and the rest will be zero or whatever, unimportant.

I fill the struct like such:

S2 g_s2[] = {
// 0x00
{ 0 },
// 0x01
{ 1 }
}

Is there some way to pad the first X number of elements so I dont have to type {0},{0},{0}, 200 times to get there?

S2 g_s2[] = { [0xf0] = 12 };

Here, we are initializing only 0xf0th element to 12, remaining elements of the array will be zero.
