CatTools CLI.modify.config to change the banner

Hi, today I tried to use Cattools to modiy the Cisco switch devices exec banner.

I found the the cattools do not support line break

for example

this will failed!

then I tried to use banner exec ^Line 1 bala bala bala....^

this will work!

but I need my banner shows in lines!

1 line is not enough

hwo to set multi lines on banner via cattools?

thanks
