Way to retrieve Darkvision or token vision with a macro?

Hey all, First DM session with R20 coming up, and I've accumulated macros for many things I think will help the game flow smoothly, including a PC Status which reports class, HP, AC, 6 stats, etc. I haven't been able to find any way by examining the OGL 5E sheet we use, or searching for any information on reporting a character's vision. Is there an attribute for Darkvision, or maybe pull it from a selected token? It's not crucial, but would be nice to have, and I just can't find where it might be. Any helpful assistance or pointers appreciated, M

You can use: @{selected|npc_senses} for npcs, but most PCs just have a racial feature among their feature list. It would probably require a specialized API script to parse out.

OK, that's pretty much what I sussed out, but wanted to ask in case I missed it somewhere. Thanks, M
