I am running out of banner space on the right side (Sidebar-1) module space and plan to run some banners across in Main-Content-1; my question is can I somehow split up the Main-Content-1 space to run 2 banners there instead of 1? I know I am getting greedy with banner space, but if I could do that, it would be more beneficial than having 1 large banner running in Main-Content-1 space. See my image which shows how I want to convert the circled banner and somehow have 2 banners in that Main-Content-1 space. Yes, I know I can add as many banner there as needed (and even in Main-Content-2), but if I can have 2 in the same space, that would be great.
Any advise is much appreciated.
