AVR-Chat

Hello, I'm trying to figure a better way to write my code
Currently for each I/O pin I have something like
.equ LCD_Enable_Port = Port C
.equ LCD_Enable = 0

and so forth for each pin. when I want to set the pint equal to one, I 
would do
sbi   LCD_Enable_Port, LCD_Enable.

I was wondering if I could combine both equates to do something like this
.equ LCD_Enable = Portc, 0

and then to set it to one I could just do
sbi LCD_Enable

Is this possible with AVR Studio's assembler? Thank you in advance.
