Regarding horizontal shifts.

[Hwaen Ch'uqi]

Greetings All,
          In this snippet, the second arpeggio overlaps with the preceding
cross-staff notation. How may I best solve this? Ideally, I should
like to shift the second half of the measure to the right. Has the
solution something to do with padding? My efforts thus far have not
yielded anything fruitful.
          Many thanks.
