Image / text / widget on homescreen - changing with macrodroid ?

[djh_wolf]

I'd like to achieve the following, for usage via macrodroid macro situations.

Either

(a) An image or widget on a homescreen, which can be altered via macro to show a different image. At the moment, my best temporary solution is to alter the entire wallpaper with macrodroid's built-in command.

or

(b) A text box, whose contents can be altered in the same way.


Basically, this is to show a small image of a house (eg) when I'm at home and a car when I'm driving. It gets a lot more interesting than that, I just wanted to illustrate with a simple example


Any help/ideas much appreciated.

TIA
