Welcome to the Q&A Forum

I personally would not. There is no need to submit an additional sitemap when you can just ping google to crawl your site at anytime. Google will put you in a que and crawl you almost immediately. I would not recommend abusing this. Only ask Google to index your website when you have new content or Google is taking to long to index current content. The more fresh content you provide, the more Google will re-visit your page and continue to index you Hope this helps!
