Dual tempo styles as needed for this song are difficult to find...although you can go into your Style editor and create your own using different variations from certain styles to make it work. Or as a secondary consideration try setting up TWO "separate" registrations utilizing different styles that you can go back & forth with to achieve the tempo changes within the song.
Also with EMC style software you can cionvert a SMF of the song into a Style too..
Good Luck.
