Boolean List

I have list of boolean data.

For example, {True,True, False, False, False, True}

I know I could dispatch them.

I dispatch the false list and did something to make them true, but how can I put them back in same order later? 

How can I select false index and use it to put them back in same order?

In this case, false's index would be (0:2),(0:3),(0:4)

And result would be {True,True,True,True,True,True}

Thanks!
