It would be very nice to have access to the trigger builder used for custom automations when selecting a trigger for an integration app.
I often use somewhat more complicated triggers (AND…) and with the standard set of trigger I can’t build this. Today I use webhooks to further detail the trigger and decide whether to call the action part or not. The full list of available triggers in the integration builder (trigger block) could easily be replaced by a single trigger builder as available in the custom automation builder.
