Shimano Flight Deck SC-6502 setup issue

[bike_boy]

Ok, so my Flight Deck SC-6502 cyclocomputer has the ability to be programmed for multi bikes.
Problem is how do I select back to bike number, say, #1? As I somehow knocked to #3.
I can't seem to find how to do this via instructions.

Found it; I had missed it on instruction page due to fine or small print.
Per instructions, put the display on any screen other than clock 'CLK'.
Then hold B button for 5 seconds. Then pres A button to rotate thru the
4 bike number selections till I get to the one I want.

When you switch say, from Bike 1 to Bike 2, does the cumulative mileage (odometer) change, or do all the bikes add on to the same odometer? The reason I ask is that I have two sets of wheels with different size tires. It would be nice to program two "bikes" for the two tire sizes and switch between the two when I change wheels. But I'd like to keep the odometer accumulating total miles since I like to track that on an annual basis.
