Passing Presentation Variables between Prompts

Few days back I got a requirement from one of my friends according to which he wanted to have the value of  Presentation Variable(selected from prompt) being passed amongst the underlying Multi Select prompts on the Dashboard.
Requirement:
Each national Promotion have NP Relase date and NP End date ,so, the requirement is to show the National Promotion in Multi Selector which the NP Relase date or NP End date between the Start date and End date (selected promt values).
Requirement

I think the above requirement can be achieved in Dropdown prompts but not in the case of Multi Select Prompts.
Any help or suggestions regarding this will be appreciated.
