There are tricks to getting around this but it requires modifying the template.

What are the tricks?
Info pages are fine like this:
Home >>Page Name
But it would be better if these where like this:
Store Pages other than Info pages:
Home >> Main Category >> Sub Category
Products:
Home >> Main Category >> Sub Category >> Product
