User Cannot manually Type LOV in Prompt Screen

Question

Hi Experts,
WEBI reports built on OLAP Universes (Universes created on SAP BW) has below problem:
As you know when user click's on Run Query or Refresh Data to run reports a prompt screen will pop up and in normal cases he has option of Selecting values for LOV's or user can type his value and run report But reports built on OLAP Universes user must select only from list of values.
Is there any way that user can directly type his value and Run Query/Report.

Thanks Rohit for the information.
Is that Lov object in your code should be Key or Text? for me key is not passing.
Below is the code reflected into Universe as a filter if we create the prompt (User Variable) at BEx Query
<OPTIONAL><FILTER KEY="[ZREG_BO]"><CONDITION OPERATORCONDITION="InList"><CONSTANT TECH_NAME="@Prompt('Enter Subscriber Region:','A',''Class\Lov Object',multi,primary_key)"/></CONDITION></FILTER></OPTIONAL>
The difference between your code and BEx code is that BEx code uses Index Key ("Primary key" instead of "free") and it uses technical name (CONSTANT TECH_NAME instead of CONSTANT NAME).
If i create prompts at Universe level instead of using the BEx Prompts (User Variables) Will there will be any performance impact ?
Your help is highly appreciated.
