How to improve supply to a poor supply hex?

[VonWulfen]

Hello all.
I plan on placing some Gebirgsjäger Mountain Troops in the mountains near Krakow.
The hex only has a supply of 1.
Is there a way to improve this supply, possibly via a supply line?
I'm unsure if keeping the Gebirgsjäger there long term is feasible.

If it is the South East corner of Poland before the axis minors are in place yea it will have low supply or no supply in bad weather. Once the Axis minors are in place it will be fine.... or should be.

How about air supply in the short run Alvaro? Or is that too expensive?

I don't believe I will get Axis minor support as I am not pushing west into France but concentrating fully on conquering Russia.
As per the original German war plan if I am not mistaken.
