[Feature Request] <Port Range should be simplify>

[devmalick]

port range should be simplify like : 80 - 500 or 80:500 regular expression is difficult to figure out

would be very handy, with tools which use a dynamic port in the range from 20000-65500 the regex look rather terrible and unreadable. this leads to users simply allowing all ports, which also means the lower ports, which is a security issue
