Is there a way to use variables within evaluate FQL?

[redheaddev]

I'd like to be able and filter incoming data for a specific value stored in a variable.
example FQL: data[id=parentId]

data = variable data from prior step
id = attribute on data object
parentId = variable set at earlier step in flow

Note: If I substitute parentid with a string literal like "1234" the query returns data.

In summary, is there a way to use the parentId token in FQL?

I'm also looking for that.
Currently, I bypass that problem with using custom tests in my requests

a similar note is to use a variable within the context of evaluate block.
