I want to set a hardcoded default value for my @RequestParam variable for sometime.

Eg: UI sends--> url.com/v1/apiName?fruits=apple,mango

```
we want -->  url.com/v1/apiName?fruits=apple,mango,banana

```

Reason for this: UI calls this API they send 2 default values(unfortunately hardcoded) we introduced 1 new value. Their deployment will take time, so for time being, we want to override their inputs.

New to APIM, so need some help.
Thanks in advance.
