Home Assistant: flexible recipients (not determined in configuration)?

[mathisdt]

Hi,
I read the documentation and have some Signal notify entries up and running, but as I use them more in automations, it feels cumbersome to always use different notify instances (per recipient). I'd really like to supply the phone number (which I currently configured via recipients: in the notify config) dynamically, per message sent. Like in the smtp notify, there I can supply a default recipient list in the config (which is used when I omit the recipients in a message), but I also can overwrite the default list by adding a recipient list to the message itself.

Is that possible with the signal integration? Or does anyone have a hint as to where to look if I wanted to create a PR for that? 😃
