Other code editor for Microsoft Word Macros/Forms/ VBA codes

Hello everyone,

Just want to ask as to what I can do on my Word Macro-Enabled Template (*.dotm). I have the template having content controls which are using macros for some automations and some forms I'm printing using the template. I was thinking of having an external Code Editor other than the built-in VBA editor of Microsoft Word so that I can edit the VBA codes outside of Microsoft Word. This is because I have been encountering a not so frequent crash in using MS Word. I experience the MS Word crash when I'm saving the word document and then just a prompt message saying "Path/File Input/Output" is shown. I click the "Ok" button of the prompt box and my Microsoft Word closes itself. It has been recurring for some time now so I was looking for an alternative code editor that I can use to specifically update the Word macros found on my Word Template

So my questions is:
Is there an available code editor that I can use to update my Word Macro-Enabled Template (*.dotm) other than Microsoft Word itself?

BTW I'm using Microsoft Word 2010

Thanks for your help
