Zoho CRM Finance Module - can I show Vendors Bills?

Zoho CRM Finance Module - can I show Vendors Bills?

I suspect that the answer is no but thought I'd ask just in case someone had a useful hack.

In CRM I can look at Customer records and see all the invoices we've sent them but when I go to the Vendor record I need to see their bills to us, not invoices we have sent them (which never happens because they are OUR suppliers).

So is the Finance module totally redundant in the Vendors section or is there a way to show their Bills instead?

I have entered these into Zoho Books already but it would be useful for other staff to see them in CRM with all the other operational info.
