Widgets: add transform offset?

Dear All,
There is a function named AddActorWorldOffset, which basically adds a value to the current locations of the actor. I wonder if there is something similar for widgets?
I’m working with images and I wish to gradually increase their height. I did this on my prototype with crappy 3D meshes using the function above mentioned but I found only render transform for widgets. Isn’t there something I look for?

Update: sod it, I managed fine without those by getting the images’ current locations and adding the speed value to them (as a float). It got the job done pretty well.
