Customize title bar

[g114112118s]

I am having same hostname in different sites. Just wondering if there is any way to customize the title bar. Current default title bar is server-1 – Secure CRT, I just want to change to , child + parent , eg Site1 + Server1 etc… blow is just as example

-Sessions
___Site1
______Server-1
______Sever -2
___Site -2
______Sever -1
______Sever-2

Thank you,
