Select roles in batch export

Is your feature request related to a problem? Please describe.
I want to be able to batch export multiple sequences and select specific roles to, say, export them without music. Right now it's impossible, with FCPX telling user they have to do it per project in the Timeline index.

Basically I want Avid's "Use track selection for export".

Describe the solution you'd like
A dialogue that would enable me to tick or untick roles to export.

This is what batch export looks like now - it's not helpful when you have lots of separate timelines to export.
