Well, the first sprite is pointless if you just want your code to read the 
second one...But, if your code uses BOTH sprites, put the sprites into 
different pointers...
EX:
....CODE HERE....
     cp 5
     jr z,showsprite1
     cp 6
     jr z,showsprite2
showsprite1:
     ld b,8          ;I am using the ionPutSprite routine...sprite is 8 high
     ld a,0          ;X coord=0
     ld l,a          ;Y coord=0
     ld ix,sprite1   ;Point to the first sprite
     call ionPutSprite     ;call the routine (any sprite routine would work, 
just fix the X & Y coord registers and the sprite pointers.)
     call ionFastCopy      ;copy the graph buffer (another is 
B_CALL(_grbufcpy) or for 83 ASM call _grbufcpy_v)
     B_CALL(_getkey)
     ret
showsprite2:
     ld b,8
     ld a,0
     ld l,a
     ld ix,sprite2
     call ionPutSprite
     call ionFastCopy
     B_CALL(_getkey)
     ret
sprite1:
     .db %00000000
     .db %00000000
     .db %00000000
     .db %00000000
     .db %00000000
     .db %00000000
     .db %00000000
     .db %00000000
sprite2:
     .db %11111111
     .db %11111111
     .db %11111111
     .db %11111111
     .db %11111111
     .db %11111111
     .db %11111111
     .db %11111111
.end
end

I hope that helped you out a bit
