Creating low value asset with categorization

Hi

I would like to categorize low value assets. As per standard procedure one asset class can be created as LVA and assign limits. My need is all the existing asset classes are having low value assets. If i make all these low value assets into one class i will be loosing the categorization like plant and machinery, computers etc. Is there any way which i can keep  this categorization after limiting these assets into LVA

Regards
