User-Inputtable Fields in key squences

It would be nice to have the ability to add user-inputted field for example on Extreme switches we would change a VLAN on a port by doing the following:

configure VLAN add port PORTNUMBER UNTAGGED/TAGGED

It would be nice to have a user-input field for this with either free-text or a pre-made list?

So in this case a pop-up box that requests:

A VLAN Name, A port number and a 2 options box for untagged or tagged

I hope this makes sense

Yes, I also need a command to “activate / jump to” an input field on a web page and then paste in text
