Hi Juan. If you are referring to the 5-1-6 Certified Reports, you can edit the form from the report printing window:

1. Select the report on the left

2. Select the Report Form in the dropdown

3. Under the Edit menu select Form Design

4. In the form editor, go to the bottom and navigate to Page 3 - this is where you can edit the page with the name and signature

5. When done, save the form and give it a unique name

6. When printing the report, you will select your customer report form

Hint: When you name the report when saving, add an underscore or 1 at the beginning of the name (i.e., 1Certified Form) so it will appear at the top of the list for the Report Form dropdown.

See KB article 223924150029747 for instructions on how to edit and save a custom report form. 

Don't know if this will be helpful, but when I did it, the properties for the signature box to be in the correct place are:

Top: 971

Width: 195

Left: 517

Height: 38

It does not appear to be in the correct place in form design; however, it prints correctly.

Also, if it's helpful, to put a checkbox automatically next to Selection A - properties are:

Top: 465

Width: 20

Left: 105
