Using a measure within a parameter

[tomperro]

Is there a way to have the first part of the parameter definition show the end date of a dates between slicer?
I would like to grab 4/17/2024 from the slicer and use it in the first part of the paramter.

I have a measure ([SelectedEndDate]) that gets me 4/17/2024 but when I use this in the paramter, it just returns the max date of my table and not the selected slicer value. 

SelectedEndDate = MAX(DateSelectionTable[DateTime])

Parameter 3 =

VAR ColumnHeaderName =[SelectedEndDate]

RETURN

{

    (ColumnHeaderName, (NAMEOF([SelectedEndDate])), 0)

}

Parameters are predefined, immutable and cannot be changed by measures.

Thank you. 

I am trying to dynamically update my table matrix headers using paramters.

I would like the headers to updated based on slicer selections.
Example:

Selected End Date Count for 4/2024	Month Prior to Selected Date Count for 03/2024	Entire Date Range Selection Count for 7/2023- 7/2024
65465	654987	654321
