I'm not really sure how to control that BRX. That's really up to the OS whether it keeps MobileSheetsPro in memory or not. On every device I've used, it does keep MobileSheetsPro in memory when switching to other apps. The only reason it wouldn't do that is if you changed settings on the tablet (typically under the developer options in the tablet settings) or if your device has limited memory so the OS is reclaiming memory by closing background applications.
