[Closed] Pickbutton Filter Parameters

Is it not possible to pass additional parameters through a pickbutton filter?

Example:

fn myPickButtonFilter obj =
(
   (classof obj.modifiers[1]) == Skin
)
fn myPickButtonFilterWithAddParam obj additionalParamProp =
(
   obj != additionalParamProp
)
rollout TestPickButtonRoll "Test PickButton"
(
   local testPickButtonBtn1Node = undefined
   pickbutton testPickButtonBtn1 "Pick Object" autoDisplay:true filter:myPickButtonFilter
   pickbutton testPickButtonBtn2 "Pick Object" enabled:false autoDisplay:true filter:myPickButtonFilterWithAddParam --How do I Pass the additionalParamProp
   on testPickButtonBtn1 picked obj do
   (
      testPickButtonBtn1Node = obj
      testPickButtonBtn2.enabled = true
   )
   on testPickButtonBtn2 picked obj do
   (
      print "Doing Some Other Stuff"
   )
)
createDialog TestPickButtonRoll

I know I could just make a global for additionalParamProp just trying to avoid it if possible here.
