Document distribution route with Read Receipt of all members of a group ?

I would like to know if it is possible to have "read receipt" on documents once they are approved ?

I'm trying to achieve this with a Route template asking for a comment task for all members of a group (not only one member of a group). For this it seems the route template needs to be set up with parallel tasks, one for each user we want a Read Receipt from.

Is there an alternative with Route, to request that all members of a group complete a comment task ? For "notification" task, all members of the group are notified, but it's then just a "notification" route, not a "read receipt" route.

Is there an alternative outside of Route ? I was hopping that Controlled Document would give such options but it doesn't seem so.

Thank you all !
