Check Boxes in Posting Preferences Memo Fields

In the AccountingLink Posting Preferences, for any Memo Fields instead of Drop downs, can we get individual check boxes for the SCM fields that can populate, so clients can customizes the data that will be included in the Memo fields populating in Intacct. I have many clients who currently what data from a couple different drop down options, and they don't have a good defaulted drop down option to choose.
