Website Button Option & edited URL

This question is in 3 parts, concerning the URL in DT Theme

1, On the listing page the URL of the business shows – can this be hidden by either a button or text link instead ?
2, Can we use a campaign URL ? for example :
https://DOMAIN NAME/?utm_source=YOURWEBSITE&utm_medium=DIRECTORY&utm_campaign=MEMBERSHIP
Where URL is entered as usual by the Listing Owner but the URL is changed so the owner can see the results in Google Analytics etc.
3, Can we make the outbound links “no-follow” ?
