Firewall Web Console Rules

[feneque]

Hello, thanks to all for pfsense. Its a great system.

I am working with pfsense and I dont know if it is posible to have more options to create rules in the firewall.
Is it posible to create new services, computers range, etc?
Is it posible to agregate traffic shaper in a rule?
Is it posible to use Firewall Builder or other products to admin firewall?
Can I export rules to file to modify?
Is it posible to configure 2 or more services and 2 or more computers in the same rule?

Thanks
