Screenhots - naming and format

Hello all,

Fresh noob here working for a company that uses ASG-RemoteDesktop 2015.

Current version installed: 8.0.5091.0

I would like to know if I can change the screenshot naming convention. 
So far it seems to be: screen_ServerName_DD_MM_YY_hh.mm.ss

Also, can I change from PNG to JPG for default screenshot format?

Thanks,
Igor
