Creating combined rules

Hi,
I was wondering if it is possible to do the following rule:
If <all> of the following conditions are met:
Name -> contains -> <some text> OR <antoher text>
Extension -> is -> pdf
I know that I could do two lines like that:
Name -> contains -> <some text>
Name -> contains -> <antoher text>
Extension -> is -> pdf
But the name only can contain one or another text. Never both at the same time and the extension is quite important. So the core of my question is: can I use operators like AND, OR, NOR etc.?
That would be very powerful.
Thanks,
Michael
