When I have a row of machines which I want to load with modules, I can just select the modules, run between the machines and ctrl-click each.

However, if the machines already have modules and I want to place better modules instead, I can't do that. I have to open the GUI of each machine and clear the inserted modules before I can put the new ones.

My suggestions: When having a module selected and ctrl-clicking a building with sockets, first all inserted modules try to move to your inventory, then the new modules are inserted.

while holding a new module in mouse shift-click old one to loot it into inventory, then right-click to insert new one.

The module slots may be visible on to of every machine. So that you see the types bit (color is enough). By clicking on them you can directly place a module. Just another method...

If I understand you correctly, I need to go into the machine GUI to do that. I'm asking for a way to do it without going into the machine GUI.

or even if you want to change from machine GUI, simply let modules replace other modules without having to manually remove the old one.
the behavior should be like replacing normal belts with fast belts: no need to remove the old one. just this will save you lot of time.
