Program Message button to group VM with EM Polycom VVX 410

I am new to FreePBX and have it setup and working. I have purchased the EM module to make programming the Polycom VVX 410 phones easier.

I have setup each extension with the shared VM box (101@device) and the message light works properly.

However, the one piece that I am missing is how to reprogram the Message button on each extension to check the group VM box. I know that I need to assign *98101 and Send to the message button but can’t seem to find a place to do that - at least not in EM. Any pointers would be greatly appreciated.!

Thanks.
