[ModelSim] How to change the prompt?

Hi All,

How is it possible to change the prompt in the ModelSim Transcript window?

I'd like it will show the current path (some echo from the execution of the pwd command).

So, instead of

VSIM>

I'd like to see something like following:

c:/unit/<unit_name>/scr/

I know how to change a prompt in Linux, but how can I change it in ModelSim?

Thank you!
