Is there a way to autofill a default password for all new connections?

Is there a way to autofill the password field with a default password for all new connections? For example, if I enter an IP address in the RVNC Connect field and hit enter, when the password dialogue comes up, it would already have a default password that we use on all of our systems filled in?

I know this is probably a shot in the dark as we're a special use case for this, but I thought I'd try.
Thanks.
