Doing Procederal Transitions versus Triggered Animations

Is there a pre-implemented way to procederal transitions on gui elements such as 'gui x, fade out on this, fade in on this, whatever'? I used to do simple ones all the time when coding up from plain C++ (which was easy mostly because it was 2d), but haven't really added anything outside of simple scrolling on and off screen ones in Torque. I'm pretty sure they can be simulated by getting an animated image (or a set of frames) drawn and flipping the controls as need be, but I'd like to try and get a decent effect without putting more weight on my overburdened artists. Is there a way in there or a suggested place to start for adding something like that? Don't have time to dedicate a lot to slipping this in as its more just a polish thing on a few of the gui elements on a short term game. Thanks in advance for advice.
