JQuery Grid Filter. Reduce "multi" filter values to only those that exist in the grid

[Daniel]

Hi!

I'm using a Grid with a key-based field  with a large list of values.
It works Ok, but when i want to filter by this field, (multi filter) appears hundreds of possible values.

¿Can I reduce the filter values to only existing options in grid elements?

Here is the example:
https://dojo.telerik.com/@larras/atuFikoP

The filter for field country allows all possible values, buy I want to limit the filtering options to the two countries that appear in the grid.

I have tried to use a new reduced collection for values, but in this case, when I add a new row, the country column has not text value and shows the id number.

¿Is possible to change dinamically the "multi" filter collection of values?

Thanks  and greetings!
