Dashboard: customomize parameter window

Hello Experts,

I have created one dashboard having parameters from BAQ. The thing is I have customized that parameter window. For example added epicombox instead there was a textbox. So user should not type in the parameter field rather than just select the values from the combo.

Problem: I am not sure how to make this customized parameter window to default for the user. As I think it is not available in menu maintenance where we can add our customization as default for other forms. Thank you in advance!
