Tick symbol in word checkbox

Hi

I am trying to see if there is a way to replace the word template default checkbox "X" symbol into the word default template checkbox.

Many forums on the subject are misread- the question is not simply adding a permanent tick symbol but using the electronic checkbox function under the word developer tab, once locked the checkboxes can be electronicly checked and the default symbol that fills the checkbox is an X, it is this default symbol I want to change to a Tick symbol

the purpose is to create a procedure checklist that staff can use on their ipads to electronicly tick off easily with a finger tap, once finished email a copy, rather than manual paper checklists-save the trees and all that, the word default template does not seem to have an option to change this X symbol however on the Word Notebook Layout template there is a perfect "note flags" tab that has customiseable checkboxes however the template format is not professional looking and appears as a actual lined page notebook (these checklists may be viewed by govt regulatory staff and a casual note book appearance isn't appropriate.

Or is there a apple alternative word type app for a professional checklist format that can be ticked off on an ipad?

Thanks

Al
