linking multiple quotes and accounts to a potential

linking multiple quotes and accounts to a potential

my setup/workflow:

- i'm a mortgage banker and i take loan requests from borrowers and send them to lenders who then provide loan quotes
- i have borrowers and lenders set up as account types
- my potentials tab is renamed loan, and there is a new one set up for every loan request.

my questions:

- for each potential on my loan tab how do i track which lender account each loan request was sent to?
- under the potential detail view i'd like to see a list of all lender accounts that have been sent the proposal. 
- on the list of accounts that the potential was sent to i'd also like to either a) make a note that the proposal was rejected or b) attach/link to a quote from each lender account?
- i'd also like to make sure that this same detail is recorded on the lender account detail page.

how can i make this happen?
