Calculated field to perform a query

This is a pretty advanced question, I assume, but here goes nothing.

We have created a "database" of sorts within Workfront using Projects. We have a single campaign that houses all of the projects and within those, they all have a custom form attached with a particular set of fields.

I want to use a separate custom form to "query" this "database" to look up values within these projects based on the "ID" of a typeahead field.

So here is essentially what I need to do.

The user selects a "Project" within a typeahead field.

Once selected, query the selected "Project" to pull "Field Value A" into a calculated field.

in SQL it would look something like this:

SELECT Field Value A

WHERE ProjectID = {typeahead id value}

I'm pretty sure there is no way to do this within WF, but I figured I'd give it a shot!
