2. I hope my English is good enough

I try to describe what my problem is.
I have downloaded my dives from my Suunto D9, everything worked fine.
But, I have some dives, which I made without my D9.
When I manually add this dives and enter the dive number, e.g. I get dive Number 1 twice.
Is it possible, that MacDive automatically updates the dive numbers?
E.g. I added my really first dive manually, (I bought my D9 one year later) and the first dive which I have downloaded from my D9 should now be (for example) 25 not 1. It is the first dive with the D9, but not my really first dive.
I hope you understand what I mean and can help me with my Problem.
Kind regards from Germany
