Hi there, @Marcel_Speckmann 
I completely get your point, thanks for sharing! We’ll have it in mind and see for more feedback from the community 
As for now, I’d like to inform you that you can add multiple apartment to 1 widget using our All-in-One Reviews app. Don’t hesitate to test it out and share your experience with us!
