They have a really nice option that actually lets the USER decide what settings should be adjusted when you change the material. So if you want to adjust the speed whenever you change the material you can do that (others may prefer to adjust the speed when they change the quality, so you can already see why it's nice to give this preference to the user).
To make the change, just go to File > Export FFF Profile, and save your profile to your hard drive. Then open the .fff file in a text editor. Scroll to the bottom and look for the <autoConfigureMaterial> sections. You just need to add the relevant settings into those sections. So, if you wanted to change the default printing speed for each material, then add the "<defaultSpeed>3600</defaultSpeed>" tag into EACH ONE of the <autoConfigureMaterial> sections (change the speed as needed). Then save and go to File > Import FFF Profile to load it back in. Now it's customized exactly how you want it!
