AssetAccountant has a suite of PDF/Excel/CSV reporting to choose from.
These are generally not customizable and sized to fit suitable outputs.
If you require reporting with more granularity that the standard suite of reports, it is always possible to export your data to Excel and sort there.
The two best ways of doing this would be to:
* run an Asset Export report, available in the Reports menu on the Asset Register screen
* run an Export from your search results on the Assets screen
