dax and weeky

I have got this table where I have calculated weeks for different dates . Day of the week here start from wednesday and ed on tuesday. Problem I am facing is in slicer and weekly percentage change for each ticket. There are different type of tickets. I want to have function for weekly percentage change based on their respective dates like closure tickets percentage change should be based on closure week for each ticket type, secondly I want to know is their any way that we can use one slicer for week where we can use date for each ticket type in just one slicer. I have made this dashboard but problem is it is based upon created date column while values for all other dates are different so I want to know is their anyway that we can use one slicer date based week slicer for all the ticketing type?
