Change Match obj

Hi i was wondering if is possible to change the target values on MATCH obj , something like

m = exists(img)
m:setTarget(L)


yes i could use m = exists(Pattern(img):targetOffset(x,y))

but the final goal is to use findAll operation and set the a new/different target on each find match

i could use this too but is NOT what i need

match = findAll(img)

for i, m in ipairs(match) do
   t = m:getTarget()
   x = t:getX() + 'random x'
   y = t:getY() + 'random y'
   click(L(x, y))
end
