Team Builder Invitation Feature

Problem:

In order to add a friend who may have just come on-line, ended their game, etc. into a currently searching Team Builder Group your only current option is to drop the group and reform. This is an unfortunate and frustrating inconvenience to both previously partied players and the randoms who have accepted to join your team. The randoms get thrown back into the search pool for another waiting period, or group leaders have to explain what is happening and manually re-invite the random players who have been waiting as well. While the latter can be done, it seems more efficient and convenient to invite friends into the remaining roles.

Question:

Would it be possible to allow us to invite people after we have started searching for designated spots? I'm illiterate when it comes to coding, so I'm not sure if this is a plausible suggestion. I'm simply trying to clearly express one of those "i wish we could do 'x'" moments has come to mind on several occasions.

Solution:

The invite message for this game mode would have options of the roles available, recipients would then accept said invite by clicking the desired available role button or the decline button as they can now.

Ending Statement: Again if this isn't possible, is old hat, or it just isn't the problem solver I have concocted in my mind, then feel free to ignore my post or critique it; otherwise, please comment with your solutions or simply upvote / participate in the poll.
