Tree Types?

Now, sometimes I want a tree that looks different without using a structure to make it, my idea is a tree type selector when you're choosing your branch and stem, so you can choose how you want it to generate, like I could choose Savanna tree (idk what it's actually called) and it would generate slanted like the Savanna tree, or I could choose red Mushroom and it would generate like the red Mushroom, thank you for looking at this and I really hope this has a chance! 😀
