InfoPath customize action when button is clicked

In an InfoPath 2013 form that accesses a custom list, I would like to add functionality to the form. When a user clicks on a button, checkbox, and/or some other item, I would like to change a 'status' value in the workflow. Basically when the item is clicked, I would like to start that part of the workflow.

Thus can you tell me if I can place a button in the 'Ribbon' that is auto generated by InfoPath and/or if I can place a button somewhere else on the form?

If so can you tell me the following when the user clicks the button and that starts the workflow?

1. 
   

   Can I place the button on the ribbon? (Can you let me know if this option is possible and how to accomplish this goal?)

   
   


2. 
   

   Can I place the button just somewhere on the form?

   
   


3. 
   

   Can I place the button in the ribbon and somewhere on the form?

   
   

Of the option you chose, can you tell me how to accomplish that goal?
