Allow to surround a parameter value with RAW()

[oscerd]

Please describe the feature that you want to propose

There are situation in which the parameter value of an endpoint option requires to be surrounded with "RAW()" in case of special character, like "+" for example. It would be nice if we could add a selectable RAW checkbox on endpoint parameters.

We can write RAW() in the Textfield but I guess it would be better if there's a button to automate this.

Maybe a checkbox [ ] Raw which then handles it
