I want to use my CRM data in Zoho to print our letters, labels, envelopes, etc for direct mail.  I have a custom field in my contact records that I use to decide who gets what types of mail.  I want to use the field to select the contacts to merge.

I installed the MS Word Plugin and got that set up fine.

I've created a template using Zoho fields and uploaded it to Templates in Zoho.  No problem there.

I now want to generate the mail merge and select contacts.  Unfortunately, the interface doesn't give me what I want.  The contact drop down just gives me a limited set of contacts (recently added, all, etc).  I can only search on name fields in the search bar.  I only see 50 contacts at a time.  

What I want is to say "select all the contacts where the custom field has the value of X or Y or Z".  Is there a way to do that in the Zoho mail merge within Word?  Can I do that within Zoho CRM itself?

You would think contact record selection would be a key feature of a mail merge and would allow for this kind of thing.

Any advice or instruction would be much appreciated.

Thanks.
