Enchance Campaigns

Not too happy with how Campains work.

I should be able to create a campaing, and attach marketing assest which are created and uploaded to the crm system.

Then throught campaigns attach leads, prospects, accounts.

Currently I have to go to each (lead, prospect, account) and attach to the campaing. It seems that the relationship linking is backwards.

I create a campain and then choose who / what I want to participate.
