Creating a model report which adds days to date cards when you adjust slicer

[Jay2077]

So I want to create a modelling report built with cards etc 

I want people to be able to filter by number of months which will in turn change a series of date cards 

Kinda like so:- 

We have a date (perhaps selcted) - drop down/slicer (3 months 6 months etc) - Procurement completed card updated - another drop down slicer 3 months, 6 month,s 9 etc - Implemenmtation date updates. 

Easy to achieve on Excel not sure how to do this on Power Bi any suggestions ?

I kinda feel like this would be a use case for What If parameters. Of course you'll have to create measures around that.

@Jay2077 Sorry, having trouble following, can you post sample data as text and expected output?

The most important parts are:
1. Sample data as text, use the table tool in the editing bar
2. Expected output from sample data
3. Explanation in words of how to get from 1. to 2.

Like so - with the aim that the user can adjust the implementation number of months and the outcome being the Implementation date 

Procurement completed  - Implementation (Number of Months) - Outpuit = Implemenetation date
