Numbering of assets migrated from AE Tax to online assets

When assets are imported from AE tax to the online Assets register they seem to come across with a random asset number. Is there any system to the order that assets are numbered? I doesn't seem to relate to the date purchased or be alphabetical.

When a depreciation report is printed from the new ledger it always seems to print by asset number (I know you can sort differently on the screen). This means that on the report assets are all jumbled up with ones from 10 or 20 years ago printing in amongst more recent purchases.

I know that you can go and edit the asset number, but with a large schedule this is a laborious process.
