[Genome] Visualization of custom track data on several chromosomes at once?

[John Major]

Is there a way to display multiple chromosomes at the same time via the 
UCSC browser? I'd like to be able to visualize several complete 
chromosomes similar to the single chrm representation which UCSC 
displays above the more detailed track window.

And, is there a way to plot custom track annotations on a zoomed out 
view of the complete chromosome? 

Thanks,
John
