Fill into multiselect input by clicking a table element (drill down)

Hi folks, I have tried to create a table drill down to insert elements into a multiselect input, that are already selected. The workflow is: User searches something by using a keyword. He then selects tokens, which are then added to the multiselect input. The mutliselect input however is used as a filter for a new search. Is there a simple way, to add selected elements to a multiselect input by a drill down. Or do I have to use java script in stead. I've already created a dashboard, which has a drilldown on a multivalue field.
