FullSimplify[8 Log[m1] - 8 Log[m2] + 4, m1 > 0 && m2 > 0]

FullSimplify[8 Log[m1] - 8 Log[m2], m1 > 0 && m2 > 0]

I get out:

8 log(m1)-8 log(m2)+4

8 log(m1/m2)

So for the second command it combines the logs using the division rule, but in the first, where there is an extra addition, it does not. Is there an option that I can turn on to always force MM to simplify that log?
