Each of your recipes is set up as an independent record, so it is not easy to do it with recipes already written. For new recipes, you can click on 'add a new recipe' to bring up your template recipe. Now go to the mash tab and click on the 'adjust temp for equip' on. On the tool ribbon will be an icon to 'set as default' which will save this current recipe as your template. you can cancel out of that recipe and test it by clicking on 'add a new recipe' again and the option on the mash tab will be checked on.
BTW, this is also a great way to preset some of the common items which you normally add to all your recipes. For example, if you almost always add Irish moss to your boil at 10 minutes, you can load that into your new recipe and click to 'save as default' and every time you start a new recipe it will always have Irish moss added at 10 minutes left in the boil.
