Regex rule problem using "start with"

[MarcoAzk]

Hello everyone
Now i have a rule like this:
{
"Endpoint": "get:/api/v1/rc/*",
"Period": "1m",
"Limit": 10
},
The calls can be something like /api/v1/rc/work_1, /api/v1/rc/work_2, ... /api/v1/rc/work_n and so on.
In this way any request is counted as unique, I need to limit all requests that starts with "work_", somewhat like:
{
"Endpoint": "get:/api/v1/rc/^work_*",
"Period": "1m",
"Limit": 10
},
But this is not working to me.
Is possible? Any suggestion please?
