Is it possible to change the DOI or Volume or Issue value outside of cls file?

I try to use jss-pdf file to generate PDF. Everything works fine except I need to modifiy jss.cls file to change DOI, Volume or Issue value at the end of paper.

Is it possible to set these values outside of jss.cls file, so it is convinent to use this template again and again. I don't want to change jss.cls file everytime I write a new document.
