Interest-Only Personal Loan

Low priority but could possibly be helpful to others too so I'll go ahead and submit for future consideration...

I would like to be able to model a Personal Loan - where I am the lender - that is repaid under an Interest-Only arrangement - not amortized. As far as I can tell this is not possible currently so I model the interest payments and final balloon payment under the Other Income Stream section. It would look and work very similar to the Investment Loan section, except that the loan is an asset instead of a liability. I did try to use the Investment Loan section, but it appears to require the PRC user be considered a borrower and not a lender (please correct me if I'm wrong). Thanks!
