How to show more than the default 4 in File-(name of account-set)

[Owen]

Dear kind, knowledgable volunteers:

We are trying to set up GnuCash for our household, and have 4 
self-employment "companies".

How can we override the default which only allows us to see the names of 
4 account-sets?

Any assistance will be appreciated.
