When creating profiles, there is no option to include an activity. Ideally, one could select "Last activity listing" and display both the activity description and the date it occurred. Beyond that, when selecting "last activity listing", you could then also choose of which type you want to display. So I could choose "Last activity listing" with a type of "meeting".
Then if I use this profile in search listings, it would display whatever my contact info I choose along with this last activity listing description and date.
