Site Address

I understand that if you are using Wix free without a plan that you give us a custom address. but is there any way we could have like say sitename.wixsite.com instead of username.wixsite.com/sitename I feel that it would look a lot cleaner and more professional for those of us who can't afford to sign up for a plan at the moment or those who are testing out wix before purchasing a plan. I just feel like that long address looks kind of spammy and confusing.
