[2022] Pausing a 'World' for older players?

I am an octogenarian and relatively new to ANNO 1800. I find it a wonderful game and it provides my memory with a real work-out. However as one advances in the game I become a little overwhelmed by dealing with a number of islands in both the Old & New World. I would find it useful if one could pause activity in one world while working in the other. I hope I've explained myself but I need to spend time setting up an island and when I return to the other world (whichever that may be) I find I have difficulty catching up with events. In addition if you employ a DLC in the game that can really be too much to handle for some of us oldies at any rate.
Perhaps your developers might consider this.
Thank you. Yorky 65
