Unfortunately there is not. A possible workaround would be to use tasks
templates https://docs.influxdata.com/kapacitor/v1.0/examples/template_tasks/
and have one task per db, not sure if that is reasonable in your case or
not. Then you could pass the database name down as a argument to the script
based on the database var:
var db string
stream
|from()
.database(db)
.measurement('a')
|where(lambda: "val"=="1")
|alert()
.crit(lambda:TRUE)
.exec('/usr/bin/python','sample.py', db)
