Platform: rest using variable in resource: "http://url/endpoint?day={{ Now }}"

I like to use a dynamic url in the rest sensor.
when saving the sensor it does not break the config check.
but i dont get any results ether.

- platform: rest
  name: rest_sensor_name
  method: GET
  resource "http://url/api/endpoint?day={{ now() }}"

is this even possible?
if not what would be an alternate way to get dynamic api calls?

Not sure why the resource parameter doesn’t accept a template. Probably just because nobody has taken the time to add that feature.

Typically what I’ve seen people do in this situation is to use the Command line sensor (with a curl command) since it allows a template.

is there some feature request i could add?
should be fairly easy to copy the rest_command parsing of urls into the sensor type, or am i wrong?

i have created a workaround.

im fetching 93 days of data from the api and use templating for loop to filter the data.
this way can fetch all my month,week,day stats from 1 api call and process them in template sensors.

but i am sure this would be a very handy feature
