How to add dropdown action list in POWL Dashboard

Hi,

I have webdynpro request submission application (Ex.material master request). This is currently starts from POWL Dashboard through a push-button. I need to add few more such request application (Ex, Vendor Request, Customer Request). Now, I want when I will click on the button, it should show a drop-down list (ex, Material, Vendor, Customer) and if I click on any one it should lead me to that particular webdynpro application.

Please suggest if this is possible.

Thanks and Regard

Arnab
