Gridfilter plugin, custom filtering for list type

Is it possible to apply custom functions to filters in a grid header somehow?

Hope it to be something like

Code:

---

filter:{type: 'list', options: [myOptionsList], fnFilter: function(...){ myFunctionGoesHere}}

---

Or atleast to get selected options and click event to filter a store manually.



Thanks!
