Auto doubling/halfing length of chord changes

[Peskatore]

Don't know if this was asked yet. I was putting in changes to a ballad for a tune using the irb Mac editor (great program!). Was thinking that the tune could be a good bossa or swing if the changes were twice as long. Is there a way to double the length of the chord changes automatically without having to re-input the chords? Or do the same in reverse (half the length of the chords)? If there is, could you let me know how to do it? If not, could you consider this idea in a future update?
