Search multiple directories with KFind or exclude specific path

Question

Is it possible to search multiple directories with KFind or to exclude a specific path? Via CLI it is easy to do so with find e.g.

find DIR1 DIR2 DIR3 -iname "*.txt"

and

find DIR -path IGNOREPATH -prune -o -print

However, I would like to do it with the graphical tool.

Thanks for your suggestions!
