I haven't used one so I can't be positive but you should be able to. It will probably smell like popcorn (and cooked cannabis) and taste not too great the next time you fire it up but if you are okay with that then I would not worry about it. You will be able to find out pretty quick if it is not a good idea.
It looks like you stuff the herb into the chamber and then put on the mouthpiece? Then you scrape out the remainder when you are finished?
Just don't forget to turn it off when you put it in your pocket.

Dried herbs not included, LOL.
Remember you can waste nothing with a vape, as long as you do not combust. The cannabinoids, if not vaporized will still be in your herb, which you can make some butter or whatever else you want to make with it. No waste. So if you stop a session early it is not a huge deal, just use it for edibles.
I have an Air as my portable. I love it. It is super easy to maintain and clean, as well as ease of use. It's not gigantic either.
