Mini pro, macros, side by side and multiview recordind

Hi everyone, I need to buy an ATEM Mini Pro to record protected meetings with social workers and families. The room has two camera[code][/code]s and I need to produce a video stream with a combined image, containing two frames. I have seen some tutorials that allow me to create a side-by-side image using the macro and DVE function. Can I save the macro and recall it directly on the ATEM Mini Pro in subsequent sessions without needing to have the PC available and access the software on the PC? Maybe by reprogramming a dedicated button or selecting the macro in some way? Another thing: can I customize the multi-view screen and record that as video output on a USB hard drive? Thanks!!
