I ended up doing just this, in a group { }

One problem was that the general PXE-class had a statement like this:

option bootfile-name "...something...";

Many of the clients that need a different setup failed to boot where this 
option was used, wireshark showed that they added strange characters to 
the end of the name of the bootfile. The solution was something like this 
in the group statement:

filename "...something else...";
option bootfile-name "";
