Accept fingerprint automaticaly secureCRT

Hello,

Is it any way to accept automaticaly the fingerprints?
The basic idea is to find a way to give a command to many servers at once.

So i thought to create a multiple session with all the connections opened them in multiple tabs and give the command at once to all the opened windows via chat window.
I saw an option /ACCEPTHOSTKEYS but i don't know how to use it.
I tried to run it via cmd SecureCrt.exe /ACCEPTHOSTKEYS but i just managed to run the program

Another way i saw in a closed thread here is to create a script and include /ACCEPTHOSTKEYS is the code.But when i try to run a sample script named "ConnectTomultipleSessionsAndSendCommands" needs a sessionList.txt file that does not exist.
I created the file but i don't know what i have to include so that i connect to all sessions(with saved username/password) and execute the commands to all sessions

Regards
