Hi guys, is there a way to "OR" prop-filters?

I'm looking for all events that occur in either LOCATION 1 or 2.

This is what I have been trying:

<ns0:comp-filter name="VCALENDAR">

<ns0:comp-filter name="VEVENT">

<ns0:time-range start="20140621T000000Z" end="20140809T000000Z" />

<ns0:prop-filter name="LOCATION">

<ns0:text-match collation="i;octet">1</ns0:text-match>

</ns0:prop-filter>

<ns0:prop-filter name="LOCATION">

<ns0:text-match collation="i;octet">2</ns0:text-match>

</ns0:prop-filter>

</ns0:comp-filter>

But this ANDs the prop-filters. Is there no way to OR or is there another way to achieve what I'm trying to do here?
