Stacking Shields

[michaj32]

Hi,
Can shields be stacked one over another on one raspberry pi 3b?
I'm building autonomous robot and I'd like to have possibility to add more motors than 4.
I see that there are pins that probably will fit manually but I'm wondering whether it will work.
And also if it is possible then how hard it is to do it from software?

im sure when I brought mine it was advertised to stack up to 40? ? ? could have gone wild on the number their, but im sure its possible to stack im looking at this myself over the next few weeks my concern is how do you code it to run motor shield A 4 motors and not motor shield B or will both all ways run linked. meaning its pointless for most builds like 4wd car/ quadcopter drone in one,
