custom field typeahead filter
I've added a Typeahead field, with the Referenced Object Type set to Project, to a custom form. I was able to create a filter to narrow down the available choices by the Template ID used to create the project. I'd like to narrow the choices down further. Is it possible to filter on the value of another custom form field (in this example, the 'Family' field)? I'd like the user to see only those projects that share the same value in 'Family' as the project they're currently working on. To clarify, 'Family' and the Typeahead field are on separate custom forms in the project. Thanks.
