2 Calanders in 1 report - Solution

Hello Community

I wanted to get any ideas for the two problems which I am having,

Problem 1 - I have a report which was previously having normal calander but now the customer wants me to implement 4-4-5 calander visual as well. The report is connected with direct query. 

Now I solution which is in my mind is.

1. I can create 2 visuals and switch between them using a bookmark. (I think best solution but the performance of the report will go down due to having more visuals on the page and in the report as well)
   1. 1 visual with normal calander
   2. 1 visual with 4-4-5 calander
   3. Switch button to change between step 1 and step 2
2. I can create 2 separate reports.(I dont think this is right as we need to dublicate 6-7 reports which is not a problem but not an ideal solution to apply.)
   1. 1 report with normal calander
   2. 1 report with 4-4-5 calander

We also need to understand that the report is a generic solution and works as a template for clients, some clients just want normal calander solution and some wants 4-4-5, so when thinking about this I feel the option 2 is ideal, let me know what you think and what could be best for me.

The 4-4-5 table uses parameter to be passed for start year and end year, so when we need to change this we have to go the semantic model setting in the service and change.

Problem 2- How can we add the value for the parameters in the power bi report itself without going to the semantic model setting and changing them, as the parameters are then picked up by the powerquery to develop the 4-4-5 table.
