Checkpoints on map for extra content and boss checkpoint

Can we have checkpoints around not corners of map in endgame but also additional checkpoints which close to extra content?
Please make additional checkpoints wich spawn close to extra content. Its a pain in ass when you need run through map again to extra content like expedition when you die.
Can you let players teleport to boss when all rares dies on map?
When boss is on map and you killed all rares, close to you spawns checkpoint but it didnt allow players teleport to boss checkpoint if they didnt activate it previously.
