Unfortunately not a "graceful" way. The available blockchain API system requires one bullet, one kill. I could take checkboxes and loop over them but you still have to accept steem connect for each one. Which means I'd build hours of programming to get the loop to work, you'd still have to select each one with a box (click #1, same as clicking button now), then simply move the act of steem connecting one by one, to after you select them. Same number of clicks for you, tons more coding to make it do it, for me, and end game? no saved time.

For what it's worth, my first pass on my own account, I removed close to 700 manually, so 77 is a cakewalk :D

Happy hunting :)
