Add amount of variables based on int?

So I’m making an infinite runner game, and I want preset formations to be made, but every time I add one, it takes a lot of time to make a new variable, write a little script around it, and then repeat that process for every other one… now the way I have it set up is that it has public gameobjects labelled “Stage1”, “Stage2” etc. but I want one variable in the top, preferably an int, that determines how many public variables are shown. (for instance if that variable is 2, you have Stage 1 and 2, but if it is 15, you have stage 1 - 15). I saw it in a video, but I can’t find it back, tried googling everywhere, also no success.

so yeah, how to make an int determine how many variables come afterwards?

Turns out it was just Variable Type
so float, int and GameObject
