Minimum row value based on visible columns

Hello,

I have a table like the one below, showing the minimum freight cost for a specific route based on the origin. Each origin is a different column.

In my database I already have the best origin for each specific route, but I want to create something more dynamic.

The idea was to make the Power BI recalculate the best origin based on the visible columns only.

For example, in a database where I have the route A, B, C, D, E and origin F1, G1, H1, I1, J1, my database shows the best route as H1:

But, for the route A, I want power BI to consider I1 as the best origin if I remove H1 from the table

I recently found a formula that brings me the best origin, but how should I adapt it in order to make it consider only the visible columns of a table that I will create?

Column =
VAR temp = {
        ( "Anchor1", Table1[Anchor_1] ),
        ( "Anchor2", Table1[Anchor_2] ),
        ( "Anchor3", Table1[Anchor_3] ),
        ( "Anchor4", Table1[Anchor_4] ) }
VAR MinValue =
    MINX ( FILTER ( temp, [Value2] <> 0 ), [Value2] )
RETURN
    MINX ( FILTER ( temp, [Value2] = MinValue ), [Value1] )

Thank you
