enhancement request - allow update to accounting treatment

There should be a way to change the treatment in the middle of the life of an investment due to change in various market and other factors which drive the accounting of an investment.  For instance, an equity deal is created with accounting treatment 'Held to Maturity', but due to unforeseen circumstances it was necessary to sell the deal and therefore would need accounting treatment of 'Available for Sale' so that the correct accounting event and accounting template is generated for the deal.
