Hi Ralf,

There is a package "BlockOptions" at 
http://library.wolfram.com/infocenter/MathSource/5549/

It is used like (you might want to know before downloading):

BlockOptions[{RowReduce},
   SetOptions[RowReduce, what->ever, you->like];
   ... RowReducing over and over again ...
(*  simply close the bracket and don't worry what you've done to the 
options of any of the functions in the list above *)
]
