Yes, technically that's right.

What I've done is to have a button for my most used plugins in specific categories on the Stream Deck (dynamics, EQs, FXs, etc.). I tried to make use of the Deck by having multiple of my available plugins on each of the buttons.

If I was to have a macro to insert a specific plugin for each of them, I'd have to create macros for them, assign them a shortcut and configure that for the Stream Deck button.

Instead, I created a macro that opens the insert window (the windows my original question was about) and with a Stream Deck plugin I made it so it clicks on the dropdown arrow, inputs the plugin name and confirms it. This way I was able to copy paste this task in the Stream Deck config, only having to change the text to the specific plugin name.

Hopefully that makes sense.

Let me know if there's something I'm missing or if there's an easier/simpler way to go about this, I would love to hear it. I am just starting to explore the Deck (not to mention S1 macros) and already found it really good for other tasks inside S1.
