(Beginner Question) Is there a way to customize unit equipment quality in the XML?

[CrazyElf]

Is there a way in the game to modify the XMLs of individual units to modify the equipment quality of that unit?

To give an example, here is the Banner Knight.

Spoiler: XML for Banner Knight

Is there a way to change the quality of equipment in the XML?

To give an example of the equipment quality (from the Wiki), would it be possible to give the knights all Hardened polearms equipment?

Polearms

Balanced	+3	+2	+450%
Hardened	+2	-	+250%
Bent	-	-1	-20%
Heavy	+1	-2	-30%
Splintered	-1	-1	-50%
Cracked	-6	-3	-70%
