Filter data using fields in a different doctype

Hi there,

Is it possible to filter data in a doctype, using fields in a different doctype? For example, I have a field called Make in Motor Doctype, to which I redirect from Prospect Doctype… In the end, I have a doctype called Policy, where I will have some information fetched from Prospect… If I want to filter using the coverages in Motor doctype in Policy, is it possible? Or is there any other way to achieve this?
Thanks in advance!
