Everything is possible, so your question would simply be a request for Espionage 3 to provide this functionality, correct?
Why does MacFort capable to do that I do not know, it might be that it came later, or it was not possible to provide the other functionality of Esp which MacFort does not have, withouth Kernel Ext etc.
I will file a feature request as described above.
Thanks for your input,
