How to make a pre-selected checkboxes?

Hi there, in the custom form creation, there are a lot of form widgets form checklists, but is there a widget that will already have boxes pre-checked before a client gets the form? 
for example, if I send an agreement form for a program we offer and I want to outline all the bonuses that are included and have it all checkboxed in advance, is there a widget for that or can I "program" any widgets to have that?
If not, am I able to have my admin fill out half the form and check box these things on the client's behave and then send them the form to fill out the rest of their info? How would this work?
