Combining text strings and send one notification

I am rewriting some of my Flows and I’d like to save things confirmed into the timeline, but I also don’t want several messages at the same time. So is it possible to combine text strings during the flow and sent them all at once?
I looked into logic and better logic but I cannot find any append action.

To illustrate it better:
I have a flow with a trigger: last person left.
Make variable "Last one gone: "
It checks if the heating is on, yes: turn off + append to variable "heating off, "
It checks if the the pet door is locked, no + append to variable "pet door locked, "
Etcetra.
At the end of the flow, whatever route it all has been trough, the message is send with all text fragments after each other.

Works well: Shared Flow | Homey

Or advanced

You just need to ensure, that there is some time difference with the “append” step. because all cards would be executed simultaneously and the outcome is undetermined.

That is so easy. Never knew you could do that with logic and text variables. Thanks! :slight_smile:
