Give me access to MSB/LSB banks from instrument parameter

I have recently added a Motif XS rack.  There is a Motif 6,7,8 device list which I am using.  I also make use of Yamaha SX editor, which is very powerful and give you access to all paramaters on any voice, and store them or keep temporary for the duration of a project. However The Motif voice editor prefers to go by Preset Bank1, Preset Bank 2, User Set 1, etc.. 

Synfire Pro wants to see MSB/LSB/ and then program#.

In short I cannot figure out how to get the MSB/LSB pair of numbers into the Instrument parameter page.  The line under the Sound; catagory should be able to accept numbers.. Right now all I can do is enter the Bank in the device list, but that is going to do no good, once I start to use over 1 instrument. (and I want to use several, each like Tyros four has it's unique MSB/LSB/PROG #. And the Logic of Yamaha's numbering syste, of banks, and programs escapes me. There are several hundred combinations for both the Motif rack and Tyros 4.

Would it be possible to make SFP have this feature.. One wouldn't have to go thru contrortions to get the correct patch sound.
