Any way to use today's date in a filter?

[troycarpenter]

I have created a filter looking for IP addresses that are deprecated AND has a custom field with a date earlier than a specific date. So far I've had to manually edit the filter each time I want to use it to change the date in the filter:

{
    "cf_expire_date__lte": [
        "2024-02-23"
    ],
    "status": [
        "deprecated"
    ]
}

I want to change the hard coded date to a variable that represents today (something like $today). This would be similar to how the $user token is provided for the permissions constraint (https://netbox.spwifi.arrisi.com/static/docs/administration/permissions/#user-token) .

Is there such a variable that would do that in a filter query?
