Last Called Sensor - different Scripts for every Echo Dot?

I use 4 Alexas in my home, i’m using the last call sensor for asking the resttime of my dishwasher or laundry.

Now i want to open/close my rollershutters(i’m using tasmota via MQTT, example close: Button 1 on, delay, Button 1 off).
In my mind it would be: Alexa, close rollershutters and the last call sensor should check which room is meant.

I know i can use the rollershutters diractly from HA to Alexa, but in german it doesn’t sound well to say “close” instead “down”.
