Currently bank feeds can only be setup for transaction accounts, however Mortgages and Long Term Liaibiltiy accounts are not "allowed".
At this day in age and given we are all about automating...
I believe that this is goverened by the banks and not MYOB. The banks choose which accounts they offer BankFeeds on and how often they provide the BankFeeds to MYOB to be imported into both AccountRight Live and MYOB Essentials.
