Change default 200 restricted variable values in Web Applicaion designer?

Hi,

How do i change the restricted variable values which is default set to 200 in "Web Application Designer" Variable screen?

In the variable screen find box, when users type lower case letters, values are not getting retrieved(ofcourse records are in upper case letters). Is there a solution where we can make settings so that variable values shows up in the search even with lower case letters?

For changing restricted values from 200, I did this.

I changed the value "maximum restricted values 200" to 20000.

in the search box, i left it blank and hit on the button "find".

I got all the values. But, can we make this automatic to get all the variable values?

thanks
