Flittering two columns with one slicer

[kha_powerbi]

I have a table with a list of clash test matrix test results therefore in the table we have for example:

clash ID	combined discipline	left discipline	right discipline	# of clashes
001_clash	AR VS AR	AR	AR	100
002_clash	AR VS DR	AR	DR	25
...	...	...	...	...
052_clash	ST VS DR	ST	DR	0
...	...	...	...	...

we have 9 disciplines in total
AR , ID, ST, ME, WS, DR, FF, EL, LA
so the rest of our table will be a combination of any two and each discipline can be either on the right or left.

Currently, I have two slicers to filter the left group, and the second to filter the right group.

However, I want the slicer to work regardless of whether its on the right or left.

For example:
slicer 1= DR slicer 2= AR
The output of Left & Right slicers: (empty since clash has AR left and DR Right opposite to the current filter)

clash ID	combined discipline	left discipline	right discipline	# of clashes

Desired output in the table

clash ID	combined discipline	left discipline	right discipline	# of clashes
002_clash	AR VS DR	AR	DR	25

yes this works for one slicer but if I add another slicer it wont work to filter out the rows with the same discipline ( eg: AR|AR) but insted it will give all values with AR in them. this does work however for different disciples with two slicers (eg: AR|DR). Is there a way to make it filter out the same discipline group?
