Select multiple parameters in document and set properties


Am new to webMethods. Please clarify my doubt. I have one document having more parameters.I want to select all the parameters at the same time and set the value for some properties like Allownull = false, content type.

Now am able to set property by selecting individual paramater.It takes time. :frowning:

Is anyother way to select multiple parameters and set the same properties?

Thanks for any help
