Prompts in SAP Dashboards Query Browser during Initial Load

Hello Experts,

I am using SAP Dashboards 4.0 SP5 and facing problem with prompts in Query Browser queries during initial load. I have come across following scenarios over here:

1. While adding the query using query browser i need to set up prompt for a region dimension. From the prompt did map the insert list of values to excel and then map the first value of List of values from excel back to selected values of Prompt. Trigger point for this query is "Refresh Before components are loaded". But in the dashboard preview the query is not taking the selected values of Prompt instead it is taking the value that is passed during the add Query.
2. I tried with another query from query browser to get the regions and trigger point for this query is also "Refresh Before components are loaded" and i am trying to pass the result values of this query in the prompt values of above query.   But in the dashboard preview the query is not taking the result values in Prompt instead it is taking the value that is passed during the add Query.
3. But if I pass a constant value say region = West from excel to prompt of Query which is working well in the dashboard preview.

So I would like to know that will SAP dashboards supports dynamic query prompts for "Refresh Before components are loaded" queries or not?

Urgent help is required and appreciated.

Thanks,
