Build an estimate from within potentials

Build an estimate from within potentials

I currently use CRM and Books.  I'd like to be able to build an estimate from within a potential.  The same as you can currently do within a contact or an account.  The estimates we build are tied to only that particular potential. The initial information being collected to build an estimate is collected within the potentials module.  Or is there already a way to do this that I'm just missing?
