Bring back Forzathon live's mechanic of others joining the same lobby when the event starts

I played fh4 after playing fh5 so know this is not coming from someone with rose tinted glasse. I honsetly believe the joining same lobby mechanic is a must have in fh5. I have played multiple forzathon lives and had a ton of active players all pop up and it brings a ton of fun and thrill to these events. No idea why this never came over with fh5 as it makes the community feel so much more alive!
