Bara en Quality of Life patch.

Jag körde på BI#och UM# men man skulle lika gärna kunna köra på BI-# och UM-# som ankare. Alternativt lägger man in underrubriker för var rekommendation.

Jag har ingen preferens endera håll men att kunna länka till en given rekommendation under arbetet känns behövt.

Vore det inte smart att ha PID namnet som ankare lite leva som man lär
