Dim Light "condition" / Disadvantage PP adjustment

As a Customizable conditions – D&D Beyond (zendesk.com) or as part of the customize options of the Senses section, have the ability to toggle on/off Dim Light (environment) or have a Adv/Disadv clickable option. 

Characters in dim light suffer disadvantage on their Perception checks (-5 on their passive Perception); such a toggle button would dynamically adjust the character sheet accordingly. 

This is especially useful in an Underdark or dungeon setting adventure, where most of the environment is either darkness or dim light. (RAW, darkness within darkvision range is also seen as dim light; so characters with darkvision still suffer that -5 PP without a source of light... which-- currently-- never translates to the digital character sheet and tends to be forgotten by players. 

For similar reasons, anything in the game that gives permanent advantage or disadvantage to a character's Perception skill (or Insight, or Investigation) should be reflected in the Senses section (passive score) (+5 / -5)
