Creating template forms for data entry into buddypress

Hi,

I manage a surf site and I was wanting to give the users the ability to give surf reports via custom form that posts the form results to the activity steam of a particular group.
Ideally this would be another tab within the group (labelled Surf Reports) the the user fills out from a form, and then hits submit, and this posts the the groups activity stream.

Is it possible to create something like this with CustomPress, and if so, could someone suggest a way of achieving this please.

Thanks
Scott
