How to modify the linker configuration file in visual studio ??

[hemanth1989]

#pragma DATA_SECTION (".myvarloc");
uint8 measurements[30];

I have created a array of size 30 in my program as above.

MEMORY
{
MYMEMORY(rw) : ORIGIN = 0x00007800, LENGTH = 5K
}

.myvars (NOLOAD) :
{
*(. myvarloc)

} > MYMEMORY

But how to add the above code in the linker file in my IDE. I am using visual studio C++
