Box Sign - specifying recipients when including multiple documents

When sending multiple documents together on Box Sign is there a way to prevent recipients (who have to sign one of the docs but not both) from receiving all the docs (ie not the ones they are not required to sign)?

For example:

I want to send a contract to be signed by an internal exec and then an external director.

There are two docs in the envelope:

i) An internal top-sheet that needs to be signed by three internal staff members, including the exec who will sign the contract doc.

ii) The contract doc itself which will be signed by the exec and then the external director.

Is there a way that I can stop the internal doc from going to the external director (so that they only see the doc they are required to sign)?

This is a feature works in DocuSign but there is no apparent way to do this in Box Sign?

Thank you
