On my tests, using BB 2010, you can use the "Edit Current Chord" to enter those large chords (more than 16 characters in a single cell), and it works. You should enter them on the notation window, so you can see them better (set it to 2 bars per screen in notation options).
** Re-visiting ** the "Edit Current Chord" will truncate it to 16, so you shouldn't revisit those long chords after you enter them, unless you want to edit them again, and add the missing characters.


BTW, another approach to this, that would likely be faster, is to just type the chords that you want without the rests..

ie)

E/B,E/F# E/D,E,G# E/B,E/F# E/D,E,G#

then, in a different bar (eg. bar 1 beat 1) , type one chord with the rests like this E...bdpg
Then choose Edit-Copy Rests, and copy from bar 1, beat 1 to the area that you want to have the rests applied to all chords. That would likely save you some typing!

Have Fun!
