Selection tool update needed

I use shapr Daily and the selection tool stays a big frustration when working with multiple parts or dwg files. When I want to clean up my .dwg I cannot select multiple lines or a area at ones. Sometimes I am selecting for more then half an hour to clean up something that can be done in other software in minutes. If the selection tool could be in the form of a eraser it would be very very helpful and safe hours of time.
