I just got promoted to branch supervisor *takesabow*

I now have 5 staff to supervise and I’m very excited to work with them. These people are joy to work with and very supportive of me when I got my promotion. I’ve been self studying to better improve my supervisory skills and reading articles like this
http://highperformanceleadership.blo...-training.html encourages me to ask the company manager if I could undergo supervisory training. Do you think it’s too much to ask because I just got promoted? I need your recommendations.
