Floating Text/Sign in Window, and Fast/Slow Intitiative macro?

Is there a way to create a text grid or token that is attached to the players' window, a la the player name/picture squares, instead of the actual vtt itself? I need a way to track initiative that isn't D&D-style. On that subject, I'm playing Shadow of the Demon Lord. DL uses a Fast/Slow initiative mechanic wherein players choose whether they are going Fast or Slow at the beginning of every new round. What would a macro look like that lets players click Fast or Slow in the macro bar at the start of every round and drop their selection in the chat window? Or, reaching a little bit, either mark their token with a status symbol(green/red) to reflect their choice, or pull a fast/slow token out of their character sheets and replace the one on the table? This is all obviously a helpless plea to the Roll20 Gods, may they hear my clicking finger's cries of agony.

As a Pro user, TokenMod could be handy for this - you can set up a macro to query the player and apply an effect to their token. Maybe look at a tint, if you're already using the token markers for status effects and the like. A red tint for fast and a yellow tint for slow, or something similar? If you're not using the initiative tracker for anything else, I guess you could use numbers to represent fast and slow? 2 for fast and 1 for slow or something? You can type text into the turn tracker (ie Fast or Slow), but I couldn't find a way to trick it into accepting text via macro. There might be an API trick that would allow this though. A simple [[?{Initiative|Fast,2|Slow,1} &{tracker}]] would achieve the numerical option, but it doesn't look great.
