Switch to "client" using keyboard maestro (focus on iterm tab with title matching substring )

I work with 4 or 5 clients, and want to "switch to" a client using the apple (top) menu.
I figured out that any macro can be made to appear in the apple top menu, which is great.

suppose my macro is named "ethan", when executed, how can I "acitvate" iTerm2.app,
and out of the preexisting tabs, focus in on the first tab which has the name of the macro (ethan) on it,
in this case it's tab named "ethan1"

By the way, here's how I set labels to tabs:

$ cat ~/bin/reset-title 
echo -ne "\033]0;"$*"\007"
