Create Measure Tied to One filter and let that filter affect nothing else??

[TDC21]

I am trying to create a report that will look at sales based on two dates that can be entered by the user. Get total sales for 1 time period, then total sales for second time period so a retaliative value can be created and sorted by. I am trying to create a measure that is hard coded to the date 1 filter then editing interactions so that the date 1 filter wont actually filter anything (except the measure) but I am not having any luck. I am pretty new to Power Bi so I am not even sure if this is the right approach. Below is an example of what I am trying to create.

Customer	Total Orders After Date 1	Total Orders After Date 2	% of sales	Difference
Cust 1	1,000,000.00 <tbody> </tbody>	150,000.00 <tbody> </tbody>	15% <tbody> </tbody>	-850,000
Cust 2	1,200,000.00 <tbody> </tbody>	850,000.00 <tbody> </tbody>	71% <tbody> </tbody>	-350,000
Cust 3	800,000.00 <tbody> </tbody>	475,000.00 <tbody> </tbody>	59% <tbody> </tbody>	-325,000
Cust 4	900,000.00 <tbody> </tbody>	- <tbody> </tbody>	0% <tbody> </tbody>	-900,000
Cust 5	200,000.00 <tbody> </tbody>	200,000.00 <tbody> </tbody>	100% <tbody> </tbody>	0

Any suggestions are greatly appreciated.
