Buffer Help 700 tweets/day

Hello guys. Recently Buffer change some stuffs, including posting only to 1 twitter account at a moment. I manage 7 accounts in my niche whit over 95k followers and I need more than 100 tweets per account in a single day, but after these changes this process takes me more than 3 hours daily comparative to 30 min from before.

Any solutions for posting on all account at the same time ?
Thank you.
