Allow for multiple entry of brokers on FFA/Bunker Trades OR allow for combination of R+L+% types

Some FFABA brokers are moving to a commission structure consisting of a (low) fixed fee + a % commission on each trade they execute for a principal. Hence to allow correct capturing of this we suggest to either i) allow for the same broker to be entered twice on an FFA or bunker trade or ii) allow to combine the rate types R+L+%

Furthermore we understand that some larger groups are using an internal service centre for execution of bunker and FFA trades which prepays external broker, GCM, etc and then recharges internally with an own mark up. To capture this correctly the suggested addition could be used as well as such recharge would consist of % , rates and/or lumpsums
