Sharing Access with Restrictions/Conditions

Please add a feature to allow users to further restrict “Share Access” based on conditions such time of documents sent/received or type of envelops. I understand that users can restrict permission to “Send”, “Edit” or “Manage” but these permission apply to all envelops/documents with no restriction.

At the moment if user “A” share access with user “B”, the entire history of user A documents will be shared. If user A is going on a holiday for a week or two and is using “Share Access” to let his/her colleague follow up matters in his/her absent, user B should not be able to have access to all user A’s document, because some of those might be personal/private. It would be great that user A has freedom to choose what type of documents user B should have access during his/her absence, or even how far back user B can see documents via this feature.
