Is it possible to automatically delete the invisible double spaces at the end of a segment?

Is there a setting that makes it possible to automatically change double spaces at the end of a segment into single spaces? These spaces are not shown in the segment itself, so I cannot do so while translating. They are in the source document, since this seems to be customary in US texts, but in Dutch, we use only one space.

Of course I can do a search and replace, but I cannot do so automatically, since there usually are a number of places in my texts where a number of spaces are deleted (if only the people writing these texts would learn how to NOT do that), so I would have to check each double space manually, which can be quite time consuming.  

So it would be so nice if Trados would give me the option to edit the intersegment spaces. Is that possible?
