Main Story stages (replay)

Let us replay all the main story stages (especially the boss stages). For some reason SG just decided to set specific stages for replay in the main story, pls allow us to replay all the stages like in the past because I still want to beat the *** out of zio, that guy literally stopped me from progressing through the main story for 3 whole months 2 years ago I think?.

Ps. W update, I almost thought it was an anniv update... I got good ml5s on the milestone but I can't do anything rn except rta because I ran out of energy and leifs.
