Logic, order to populate tiles (auto tiling)

Sorry english, this is hard to explain for me: I create a layout, I "open stuff" and I can see the layout gets populated from top right and clockwise. Okay. I create another layout, but then the order in which the "stuff I open" gets in the tiles seems different. So question, is there an option to decide which tile in a layout is 1st, 2nd, 3rd, etc.?

If there is not such a thing, I would love to have the option, so for example, when having 1 big tile and other small 2 tiles, so the first thing you open (ie firefox) gets into the big tile not the smaller ones. I hope it makes sense <3

Thanks for this cherry on top linux experience.
