toggling port pins through an element in a structure

Here is what I am trying to do:

sbit PORT_1_0 = P1^0;

void main ()
{ PORT_1_0 = 1; while(1) { PORT_1_0 =~ PORT_1_0; }
}

Now this is as simple as it gets.
The question is, is it possible to do the same thing using an element of a struct?

Something like:

struct abc
{ unsigned char bit : 1;
};

struct bit bit_array[24];

bit_array[0].bit = P1^0; //Assign the port pin to be toggled

//and then the toggling here.

Basically, how to assign a port pin to the bit in a struct? I am doing this because based on the address of a frame, I need to decide which pin is to be set.
I hope you get the question.
