TellMeWhen addon - How to show spells that are charged and instant

I am wanting to get more into raiding and m+ and am trying to configure TellMeWhen to help track spell cooldowns. Does anyone who uses this mod know how to get it to show spells that have a certain number of stacks on them that make them instant? As an enhance shammy, 5 stacks of maelstrom weapon makes spells like elemental blast instant, but I can’t get it to show a highlighted border around it like it does on my bartender bars. I assume it is in the notifications tab but am not sure what to use, as the “on charges gained” feature doesn’t do it. Any help is greatly appreciated!

Weak Auras is almost required for raiding and M+ anymore and you can do all of this with that addon. I’m a fan of not having addons that duplicate functionality (unless they’re from the same developer and that developer is careful to make them mesh well).

I don’t know TMW - I tried it once a few years back and abandoned it in favor of WA.

If you need help setting up the auras, ping me on my battletag ID and I’ll help. Kaldara#11970.

Sorry this wasn’t an answer to the question you actually asked, but it might be helpful.
