NASM: little-endian WORD constant

I want to make WORD variable in little endian without manually converting it, for example:

SECTION .data
    variable1: dw 2  ; <-- How to make 2 little-endian without manually writing db 0x02, 0x00?

Maybe NASM has builtin macro or you can suggest your one?

>Solution :

Something along these lines should work (link shows another approach)

MACRO M_swap16 operand
 LOCAL result
 result = (((operand and 0FFh) shl 8) or ((operand and 0FF00h) shr 8))
 exitm %result
ENDM

Does TASM allow a macro to be used as an operand
