Not that I know of. Checkboxes work exactly the same as any other input element, so their would be no reason to do a tutorial specific to checkboxes.
If you are using MySQLi, then you don't even need to use multiple insert. The standard insert server behavior will work with arrays like checkbox groups.
Just:
1) Add your checkbox to the page and name it with brackets like: <input type="checkbox" name="toinsert[]">
2) Bind the value of the checkbox to the recordset and use a Repeat Region Server Behavior to repeat the recordset for all of the rows
3) Apply the insert server behavior and use the "array" version of the checkbox to insert and one row will be inserted for each value checked automatically.
The best thing to do is try and post here when you get stuck.
