Making a title template/macro with multiple logos

Hi!
I am trying to make a title template with fusion that holds many logotypes in one composition made with the fusion page and the via macro to a template.
I would like to get it working in a way that after dragging the template from titles into the timeline I can choose to activate one of the logos within the inspector.

I would rather have it this way instead of creating many single logotype titles in the toolbox.

I have tried to add the png:s in a fusion comp thinking i could use merge to get them all show and then deactivate display before making a macro to import as template. And then in the template be able to activate the correct logo for the current project.
But I cannot figure out how to connect image files with merges in the right way.

Yes, I am a newbie so I probably cannot explain very well. But to compare with for example layers in photoshop: it is like having one logo per layer in a big group and activate just the layer with the right logo.

Here is what´s not working for me in fusion:

I have tried to search for tutorials solving this but failed to find any.
Is it possible to solve?
Thanks in advance for any help!

I think this video might help.

That's really interesting! But is there any solution that doesn´t require expressions/programming to solve such a simple task (switching between 40 or so png:s in the same timeline object)?

Well, I think I´ll go for good enough for now. Created a transparent logo-file of same size as the real files. Put this on a track on the timeline and use replace file option in the media pool to replace the transparent with the real logo from a folder on the computer with all the logos. Seems to work.
