Hi Hans,
This is a fairly simple task once you know how.
Using the "evalute expression" converter you can combine/manipulate several strings into one. In you case you want to combine the existing string in your attribue with something just extracted.
Every attribute in which you can store data, can also be called directly in converters using this convertion: objectname.attributename (e.g. ScratchPad.shortText1). Likewise your current extraction can be called using INPUT. So now you can combine these two viia the simple expression:
INPUT + objectname.attributename
Kind regards
The question is not:
"Is it possible for a robot to ..." but rather:
"How do I setup a robot to ..."
