Modify subscribed calendars (event fields)?

I subscribe to several calendars from (a service for importing fixtures for your favourite soccer team in your digital calendar; scheduling changes and live scores will be applied automatically), but would like to modify/filter the events they provide (I would like to clear the DESCRIPTION field of each event).

Can this be done (for a subscribed calendar)? How?

Reason for asking: I don’t like this “useless”/annoying info in the description of each event…
