Strip replace command for XML feed using All Import plugin

I have a XML feed that import real estate listings with All Import. The XML feed has codes that need to be replaces with words, so I have the following strip replace commands: [str_replace("RS", "for sale", {offering_type[1]})],[str_replace("RR", "for rent", {offering_type[1]})],[str_replace("CR", "for rent", {offering_type[1]})],[str_replace("CS", "for sale", {offering_type[1]})] The only problem is that they are multiple commands separated by comma and I need to combine them into one single command
