Permission level

Would it be possible to have a permission level where people are able to edit only services they have been assigned to?

For example we have different worship leaders and it would be really helpful for them to be able to add the songs they have chosen for that service (and then have the ability to add them during services on the fly via Music Stand), but not the other services they're not involved with. It would dramatically cut down on the risk of things being accidentally added/removed from the wrong services!
