It would be nice to invite a group to a pull request. Often people are unsure who to invite to the pull request but they know what team is responsible for the feature. And members of the teams also changes. It would also make it faster so you don't have to lookup the team members of a group and add every member. If instead there was a possibility to add a team to the pull request it would make the flow much faster. There are different way of implementing this but one way would just add the team members if you add the team.
