Can I change which points are selected programmatically?

Hi, a short question, with hopefully an easy answer:

Similar to the Bokeh question I would really like to set the active selection (~ box_select) in a Holoviews figure.
Is there a way to overwrite the selection?
I can think of a way by setting: streams.Selection1D.index = myindex, but this value cannot be modified.

ps: I failed to get the bokeh solution to work and I cant help but think there could be an better way in Holoview.
