Use Zoho CRM Account fields to filter for a Campaigns mailing list?

We base our mailing list off of Zoho CRM, and would like to filter by various fields in both Accounts and Contact to create the mailing lists.

For example, to select Contacts of Accounts where the company size > $xxxx revenue (where the revenue field is on the Acccount record).

It does not appear that we can currently filter by fields at the Account level. So, we have to duplicate some information from the Account to the Contact records, which should be unnecessary in a relational database.

Is it planned in the future to allow this kind of filtering from Account fields?

Thanks in advance.
