resellers and trial sites

[eastcoast]

Can you assign a different "trial site" plan to a reseller ? Or, if not, is there a way to eliminate some of the templates included in the resellers plan. For example, if I have a "hardware store" website hosting service and a "plumbing" website hosting service wants to be a reseller, can I eliminate all the electrical, carpentry, painting, etc. templates and just provide my reseller with just the "plumbing" templates for his/her trial plan while keeping all the templates intact on my own trial plan on my site ?
