Cannot add more that 10 services to a server monitor?

Cannot add more that 10 services to a server monitor?

I am trying to add services to a server monitor.  I am unable to add more than 10 windows services or process per server monitor.

Is there something I can do to be able to add more than 10?  We monitor a lot of services in our environment and if that is a hard limit that would be a problem for us.  Any insight would be helpful.
